Answer 1

Answer:

Step-by-step explanation

$\frac{3}{8}=\frac{a}{2}\\\\\frac{3}{8}*2=a\\\\a=\frac{3}{4}\\\\\\\frac{3}{8}=\frac{15}{b}\\\\ 3*b=15*8\\\\b=\frac{15*8}{3}\\\\b=5*8\\\\b=40$

Answer 2

Answer:a=3/4 and b=40

Step-by-step explanation:

To find 3/8=a/2=15/b

Firstly find a

3/8=a/2

Cross multiply

8a=3×2

8a=6

a=6/8

a=3/4

To find b

a/2=15/b

Where a=3/4

3/4/2=15/b

3/8=15/b

Cross multiply

3b=120

b=40

a=3/4 and b=40
