No

Explanation:

Convert 2/5 and 5/8 to fractions with the same denominator. The least common multiple of 5 and 8 is 40.

2/5*8/8=16/40

5/8*5/5=25/40

Clearly, 5/8>2/5.

No

Explanation:

When b and d are non-zero:

a/b=c/d" " if and only if " "ad=bc

In our example:

2*8 = 16 != 25=5*5

So:

2/5 != 5/8

A sort of cheat way:

5/8 is bigger so the answer is no

Explanation:

If 2/5 was equal to 5/8 then dividing one into the other will give the answer of 1

Consider 2/5-:5/8

If the answer is less than 1 then 5/8 is bigger.
If the answer is more that 1 the 5/8 is maller.

2/5-:5/8->2/5xx8/5" "=" "16/25 which is less than 1

So 5/8 is bigger
