Question

Please help, this makes no sense to me.

Answer 1

Explanation:

Keep in mind

-the fractions have to be EQUAL if they are equivalent fractions

-we multiply the numerator and denominator by the SAME number

-when comparing fractions think (how many slices / the size of the slice ) = (15 slices / size 20) is more than (12 slices / size 20)

Answer 2

`\textsf{left} \ \ (3 * 5)/(4 * 5)=(15)/(20)\\\\\\\ \textsf{right} \ \ (3 * 4)/(5 * 4)=(12)/(20)\\\\\\(15)/(20)>(12)/(20) \ ,\textsf{so} \ \frac34>\frac35`
