Without knowing your grade or class, I think this problem is to teach you the correct order of doing stuff in a big problem.

1. First you do the parts in parentheses: so 3 divide 4=.75 and 2 divide 3=.66
Then the problem should look like 3(.75) times 8(.66)

2. Then you multiply the number in the parentheses by the number to the left of it: so 3 times .75 = 2.25 and 8 times .66 = 5.28
Then the problem looks like 2.25 times 5.28

3. Multiply what you have and 11.88 should be the answer

I AM TRYING TO UNDERSTAND BINARY


Where to start. Most things we do in math are in base 10, probably because we have 10 fingers. Instead of base 10, binary is base 2. In computers, binary rules because a bit can be set to ON or OFF, 1 being ON, and 0 being OFF.

So the next thing is counting. 0 1 10 11 100 101 110 111 1000 1001
Decimal equivalent 0 1 2 3 4 5 6 7 8 9

How to convert from binary to decimal? Line up the columns and multiply down. For example, 1101. The columns, starting from the right are 2^0, 2^1, 2^2, 2^3, reading ^ as exponent.

See if I can line these up. 1 1 0 1
2^3 2^2 2^1 2^0
8 4 2 1
multiplying down 8 4 0 1

Next step is to add them up. 8+4+1 = 13!

Going the other way, we have to divide by the largest 2^x number, so what is left over and continue dividing until nothing is left.

For example, 56. 2^5 (32) is the largest 2^x number that goes into 56, so we put a 1 in this column. Our remainder is 24. 2^4 (16) goes into this once, so we put a 1 in this column. Our remainder is 8. 2^3(8) goes into this once, so we put a 1 in this column. Now the remainder is 0 so we put a 0 in the 2^2 (4) column, 2^1(2) column, and 2^0 (1) column.

We end up with 111000.

Let me know if you have any questions.

Good luck.

This answer is correct. 4/12 divided by 2/2= 1/3
The reciprocal of 2/2 is 2/2
Then you multiply straight across and reduce to get 1/3

What are 4 different fractions that are equal to 1 1/2


Hi Anonymous,
You can make equivalent fractions by multiplying or dividing both top and bottom by the same amount, but only multiply or divide, never add or subtract, to get an equivalent fraction.
I've only shown the fraction part of your question as 1 is a whole number.
1/2 = 2/4, or 4/8, or 8/16 or 16/32 or 32/64 & so on.
Going the other way, dividing 2/4 by 2 will give 1/2.
But, only divide when the top and bottom would still be whole numbers, for instance you wouldn't use divide for odd number fractions, for example 1/3 or 3/5 etc.
Trust this helps, best regards Alan

What is 67,872 divided by 24, step by step?


First, find out how many whole times 24 will go into 67
67/24 = 2 with a remainder that we don't care about. Write down 2
Next, multiply that answer (2) by 24 2 X 24=48
Subtract that 48 from 67 67-48=19
bring down next digit (8) append to the19 198
divide 24 into 198 198/24=8 Write down 8
multiply that answer by 24 8 X 24 =192
Subtract that 192 from 198 198 - 192 = 6
bring down next digit (7) append to the 6 67
divide 24 into 67 67/24 =2 Write down 2
multiply that answer by 24 2 X 24 = 48
subtract 48 from 67 27-24=19
bring down next digit (2)append to the 19 192
divide 24 into 192 192/24 = 8 Write down 8
multiply that answer by 24 24 X 8=192
subtract 192 from 192 192-192=0 You're done!
Your answer is the numbers you wrote down after the divisions = 2848

How to divide mixed numbers


Convert both to improper fractions, divide, then simplify.

3 3/4 is 15/4, 1 1/8 is 9/8. Dividing 15/4 by 9/8 is 120/36. Reducing to lowest terms gives 10/3, which is 3 and 1/3.

3/8-7/2= how do I get the answer I know the answer but want to know hot to get it


You convert the fractions so they have the same denominator (bottom number) then subtract the numerators (top numbers). 7/2 is the same as 28/8 (8 divided by 2 = 4. 4 times 7 = 28, so the equivalent fraction is 28/8. You can check by dividing 8 into 28 = 3 1/2 = 7/2. So, 3/8 - 28/8 = negative 25/8 or 3 1/8.

2X+4Y=-8


2x + 4y = -8 ; divide each side by 2
x + 2y = -4 ; subtract x from both sides
2y = -4 - x ; rearrange
2y = -1x -4 ; divide each side by 2
y = -1/2x - 2 ; relate to slope/intercept form of line (y=mx+b)

implies there are multiple solutions that fall along a line with slope -1/2 and y intercept of -2

How to calculate ratio number


Ratios are usually written as xx/1 such as 8 to 1 or 4 to 1 so that one is the base number. If you have 8 black sheep out of 64 then it's ration is 64/8 but you want to reduce the 8 to 1 so divide 8 by 8=1. now you have to do the same thing to the the other side of the equation so you have to divide 64 by 8 = 8 or to simplify this divide the first number by the last = the radio. Thus 64/8 = 8/1 on a more difficult scale let's do 6888/123 is 6888 divided by 123 or 56 to 1

Divide 56Kg in the ratio of 4:3


You just need to divide the 56 by 7 in order to get the right base, then multiply that result by 4 and then 3 in order to get the answers. So...

56/7 is 8. 8*4 is 32, and 8*3 is 24.

32Kg and 24Kg

You can do this with algebra as well, equation is 4x + 3x = 56.
