You have to multiply 3 by 10 and 8 by 3, then subtract them

30/80 - 24/80 = 6/80

then simplify

6/2 and 80/2

Answer:

m = $\frac{7}{3}$

Step-by-step explanation:

Given

$\frac{2}{3}$ + $\frac{3m}{5}$ = $\frac{31}{15}$

Multiply through by 15 to clear the fractions

15 is the lowest common multiple of 3, 5 and 15

10 + 9m = 31 ( subtract 10 from both sides )

9m = 21 ( divide both sides by 9 )

m = $\frac{21}{9}$ = $\frac{7}{3}$
