x% of 42 is 29.4
y% of 63 is 31.5
Step-by-step explanation:
To find the solution, you need to form the equation,
x% of 42 is 29.4
(x/100) x 42 = 29.4
x/100 =
x = () x 100
x = x 100
x =
x = 70
Hence, 70% of 42 is 29.4.
y% of 63 is 31.5
(y/100) x 63 = 31.5
x/100 =
x = () x 100
x = x 100
x =
x = 50
Hence, 50% of 63 is 31.5.
