Question

Find the value of x and y so that both proportions will be correct: x/y = 3/8 and y/25 = 6.4/5

Answer 1

Answer:

x = 12 and y = 32

Step-by-step explanation:

$\frac{y}{25}=\frac{6.4}{5}\\\\\y=\frac{6.4}{5}*25\\\\y=6.4*5\\\\y=32$

$\frac{x}{y}=\frac{3}{8}$

Plug in the value of y

$\frac{x}{32}=\frac{3}{8}\\\\x*8=3*32\\x=\frac{3*32}{8}\\\\x=3*4\\\\x=12$
