Question

The sum of three-fifth of w and three-fourths of g ,minus 5

Answer 1

`=(12w+15g-100)/(20)`

Explanation:

Three-fifth of w is 3/5 of w

`=(3)/(5) *w=(3)/(5) w`

Three-fourths of g is three-quarters of g

`=(3)/(4) *g=(3)/(4) g`

find the sum of the fractions then subtract 5

`=(3)/(5)w-(3)/(4) g-5\\\\\\=(3)/(5)w-(3)/(4)g-(5)/(1)`

The LCM here is 20 i.e 5*4

=
`(3)/(5) w+(3)/(4)g-(5)/(1)=(12w+15g-100)/(20) \\`
