Answer:
Step-by-step explanation
[tex]\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[/tex]
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
3b=120
b=40
a=3/4 and b=40
