Of course 18 is the correct answer. You can do anything to an equation as long as you do it to both sides. So to solve 9/4 divided by 1/8 multiply both sides by 8/1. The 1/8 portion becomes 8/8 which is 1. The 9/4 portion becomes 72/4 which of course equals 18.

Posted on Oct 15, 2014

9/4 * 8 = 72/4 = 18

or

9/4 * 8/1 = 9/1 * 2/1 (after cancelling) = 18/1

Multiply 9/4 by 8 to get 18.

No it isn't as 1,2,4,8 can be used to divide it prime's are only dividable by 1 or itself only

20 is 1,2,4,5,10

20 is 1,2,4,5,10

Hi Tammy:

Here's what I would do.

1) 1500 divided by 3 equals 500

that would leave 124

2) 120 divided by 3 equals 40

That leaves 4

3) 4 divided by 3 equals 1

with 1 remaining.

putting the quotients together you get 541

with 1 remaining.

All can be done mentally with no calculator and basic multiplication tables that most school children memorize.

Is this what you were looking for?

Cheerfuls.

First make 1 2/3 into a mixed fraction and then divide it by 3.

To make 1 2/3 into a mixed fraction, multiply the whole number, in this case, 1, by the denominator (the bottom number) and then add the numerator (the top number). Thus, we get (1*3+2)/3 or 5/3. Now we have to take 5/3 and divide it by 3. I was taught that in this case, dividing by 3 is the same as multiplying by 1/3. 5/3 x 1/3 = 5/9.

If you have access to a calculator you can always check this. On the calculator, do 2 divided by 3 and add 1. Now take that answer and divide by 3. Write down this answer. Now take 5 and divide by 9. Write down this answer. They should be the same.

Good luck.

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

This calculator does not have a key that you can use to find the prime factor of an integer.

You can however use the calculator to find the factors

1.** If number is even divide it by 2**

Keep dividing by 2, while keeping track of how many times you divided by 2.

If you divided 5 times by 2 before getting an odd number, then your first factor is 2^5

2.**Now try dividing by 3**, keep track of the number of times you divided by 3 before you could not divide by 3 any more. If you divided 0 times by 3, your second factor is 3^0, or 1 and 3 is not a factor.

If you divided 4 times by 3, your second factor is 3^4

3.**Divide by 5,** until you can't any more. Keep track of the number of times you divided by 5.

4. Divide by all other prime numbers 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, etc. For each prime number, keep track of how many times you divided by it, until you could not any more.

**Example: 23100**

*Division by 2*

23100/2=11550 ---------> 1 division by 2

11550/2=5775 ----------> 2 divisions by 2

Note that 5775 is not divisible by 2.** No more divisions by 2. **

First factor is 2^2

*Division by 3:*

5775/3=1925 ----------> 1 division by 3

1925/3=641. 66667 Not an integer. No more divisions by 3.

**2nd factor is 3^1**

*Division by 5 (number ends in 5)*

1925/5 =385 -------> 1 division by 5

385/5=77 ----------> 2 divisions by 5 and no more (quotient does not end in 0 or 5)

**3rd factor is 5^2**

*Division by 7 *

77/7=11 --------> 1 division by 7, and no more

**4th factor is 7^1=7**

*Division by 11*

11/11=1

**5th factor is 11^1=11**

Assembling the factors 2^2, 3^1, 5^2, 7, 11

Prime factorization of 23100 is

**23100=(2^2)(3)(5^2)(7)11**

1 divided by 3 is one-third and 3 divided by 3 is one.

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.

For any polynomial A(x) there is P(x)=A(x)(x-1)(x-2)+2 and this polynomial fulfills above requirements.

Then, remainder of P(x) divide by (x-1)(x-2) is also 2!

Then, remainder of P(x) divide by (x-1)(x-2) is also 2!
