What is 1 divided by 3 and 3 divided by 3 - The Learning Company Achieve! Math & Science Grades 1-3 (381933) for PC, Mac

First add 2/3 (4/6) + 1/2 (3/6) = (7/6) = 1.1666
6 divided by 1.1666 = 5.1431

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?

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.

To divide fractions proceed as you usually do with any number. Just make sure to enclose each fraction in parentheses. You may want to remember a simple rule: To divide a fraction by another, multiply the first one by the reciprocal of the other:
(a/b)/(c/d)=(ad/bc)

One trick I use is to add up all the digits and divide by 3. If the answer is even, (a multiple of 3), it's not a prime number.
57 = 5+7=12. 12 divides by 3 evenly (4), is not a prime.
59 = 5+9=14. 14 does not divide by 3 evenly, therefore prime.
999 = 9+9+9=27 divide by 3 = 9, not prime
997 = 9+9+7=25 divide by 3=8.3 not even and is prime

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

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.

Of course you can divide by a log. As an example, to divide 2 by the log of 3, press
2 / 3 LOG =
To divide 2 by the natural log of 3, press
2 / 3 LN =

Hello! First; 5 divided by 6= .8333+1= 1.8333


Then; Take 3/4 3 divided by 4= .750


Then; Divide .750 by 1.833= .40909


Ans. = .40909
