Question

Find my number if 3/8 of it is 24.

I'm usually good at math and can solve this easily but today I'm having a brain fart....

Answer 1

The number is 32

Explanation:

Let the number be x

`(3)/(4) * x = 24 \\ (3x)/(4) = 24 \\ cross \: multiply \\ 3x = 24 * 4 \\ 3x = 96 \\ x = (96)/(3) \\ x = 32`

Answer 2

64

Explanation:

`let \: the \: number = y \\ from \: the \: queston \: (3)/(8) \: of \: y = 24 \\ (3)/(8) * y = 24 \\ (3y)/(8) = 24 \\ 3y = 8 * 24 \\ 3y = 192 \\ divide \: bothsides \: by \: 3 \\ (3y)/(3) = (192)/(3) \\ y = 64 \\ therefore \: \: the \: number \: is \: 64`
