Question

if one-fifth of number is subtract from one-third of that number the result is 6.find the number

Answer 1

basically,
x/3-x/5=6
lcm=15
so it will become
2x/15=6
then x will be 45
so the number is 45

Answer 2

Hi ,

Let the number = x

One - fifths of the number = x/5

One - third of the number = x/3

According to the problem given,

x/3 - x/5 = 6

Multiply each term with 15 ,

15x / 3 - 15x / 5 = 6 × 15

5x - 3x = 90

2x = 90

x = 90/2

x = 45

Therefore ,

Required number = x = 45

I hope this helps you.
