Answer:
Step-by-step explanation:
1/4 inch to 3/8 ft = x inches to 1 ft
(1/4) / (3/8) = x / 1
cross multiply because this is a proportion
3/8x = 1/4
x = 1/4 * 8/3
x = 8/12 which reduces to 2/3 inches <==

Answer:
x = 18 and x = 36
Step-by-step explanation:
let unknown value is x
6:x = 1:3
product of means = product of extremes
6*3 = 1 *x
18 = x
x:30=8:5
product of means = product of extremes
5x=180
x=180/5
x=36
