Is 7/5 greater than or lesser than 2/8

First you have to make these two fractions have the same denominator, in order for us to be able to compare them without fear of mistake

one number both 5 and 8 have in common is 40

so our process would go something like this:

5 * 8 = 40

7 * 8 = 56

7/5 becomes 56/40

8 * 5 = 40

2 * 5 = 10

2/8 becomes 10/40

now you can either compare them as fractions, or as decimals

since 10 is less than 56 we know that 10/40 is less than 56/40

in decimal form

10/40 would be 0.25

56/40 would be 1.4

0.25 is closer to 0

1.4 is closer to 1

0.25 is less than 1.4

answer: 7/5 is greater than 2/8
