7+3=10

10 units=280
divide by 10
1unit=28

smaller is 3 units
1unit=28
times 3 both sides
3unit=84

smaller is 84

$\frac{5}{7} \: - \: \frac{3}{2}$

First, we find the lowest common denominator which is "14", we put it in the common numerator.

$\frac{10 \: - \: 21}{14}$

$\boxed{ \bold{- \frac{11}{14} }}$
