Question

three fifth of one fourth of a number is 90. the number is?

Answer 1

Let the number be y

.

Three fifth of one fourth of a number is 90.

⇒ 3/5 x 1/4 x y = 90

Evaluate LHS:

⇒3/20 y = 90

Multiply both sides by 20:

⇒ 3y = 1800

Divide both sides by 3:

⇒ y = 600

Answer: The number is 600.

Answer 2

Hey there!

Let us take the number as ' m '

if we get the para into equation

we get

( 3 ÷ 5 ) × ( 1 ÷ 4 ) × ( m ) = 90

( 3 ÷ 20 ) × ( m ) = 90

3m ÷ 20 = 90

3m = 20 × 90

m = ( 20 × 90 ) ÷ 3

m = 20 × 30

m = 600

The number is 600

Hope my answer helps!
