Question

One fourth of a number is added to one fifth of the same number. If the result is 18, find the number

Answer 1

Answer:

(¼)x + (1/5)x=18

(9x) ÷ 20 = 18

9x = 360

X= 40

Answer 2

Answer:

$40$

Step-by-step explanation:

Let $x$ be the number.

$\frac{1}{4} x+\frac{1}{5} x=18$

$\frac{9}{20} x=18$

$x=18 \times \frac{20}{9}$

$x=40$
