To decide the order of the fractions from largest to smallest, it is simpler to make all of the denominators the same number. To do this, I would find the number that each of the denominators is divisible by. In this instance, the number would be 20, because 20 is divisible by 10, 4, and 5. Divisible means that the number is capable of being divided without a remainder.


Next, I would multiple the numerator by the number I multiplied the denominator to make sure the fraction is the same. To get 20, I multiplied 10 by 2. Therefore, I must multiply 7 by 2, which is 14. 7/10 becomes 14/20. To get 20, I multiplied 4 by 5. Therefore, I must multiply 3 by 5, which is 15. 3/4 becomes 15/20. Last, to get 20, I multiplied 5 by 4. Therefore, I must multiply 4 by 4, which is 16. 4/5 becomes 16/20.


Therefore, the order of the fractions from largest to smallest is as follows: 4/5, 3/4, 7/10.

Step 1: all the fractions need to have the same denominator (bottom number)

We find a number of which all three fractions are a factor, in this case 10, 4 & 5 are all factors of 20, so we can convert them all to 20ths by completing the same operations on both the top and bottom numbers:


7 14

10 multiply by 2 20


3 15

4 multiply by 5 20


4 16

5 multiply by 4 20


Step 2: put the converted fractions in the correct order


16 15 14

20 20 20


Step 3: convert them back


4 3 7

5 4 10

4/5,7/10,3/4

When you divide the fraction,

For example, 4/5=0.8 it's closer to one and when you do the orders same way then you can get the largest fraction
