Question

Why is 5/7 less than 8/10

Answer 1

So this question is just a comparison problem.
If you split a chocolate bar into seven pieces, and ate 5 of them, you would have eaten less than if it were split into 10 pieces and you ate 8.

Another way to see this is if we did it mathematically.
5/7*10/10 = 50/70
8/10*7/7 = 56/70
Now that the denominators are the same, you can compare 50 to 56 and obviously, 50 is smaller than 56. 

Hope this helps! If you have any questions, just ask!

Answer 2

Because when u have come denominators such as 70 5/7 would be 50/70 and 8/10 would be 56/70&

50/70<56/70
