Question

estion 8 (BECE 2002A Ques, Ic) One-fourth of a number is added to one-fifth of the number. If the result is 18, find the number​

Answer 1

Step-by-step explanation:

Let's call the number "x".

According to the problem statement, we can set up the equation:

1/4x + 1/5x = 18

To solve for x, we need to first find a common denominator, which is 20 in this case:

(1/4)(20)x + (1/5)(20)x = 18(20)

5x + 4x = 360

9x = 360

x = 40

Therefore, the number is 40.
