Question

The difference between 1/2 o a number and 1/5 of the same number is 24. Find the number

Answer 1

the difference in two numbers is |a-b| or the larger minus the smaller.
so you have the difference of two numbers
one is (1/2) of some number and the other is (1/5) of some number
1/2>1/5 so
1/2x-1/5x=24

Answer 2

set \[\frac{ 1 }{ 2 }x-\frac{1}{5}x=24\]

Answer 3

Multiply everythnig by 10 to get rid of the fractions:\[5x-2x=240\] and solve for x
