Question

Solve the equation.


`(1)/(5)` + W = 7
`(1)/(3)`

A: w = 7
`(8)/(15)`
B: w = 6
`(2)/(15)`
C: w = 7
`(2)/(15)`
D: w = 7
`(1)/(4)`

Answer 1

1/5 + W = 7 1/3

subtract 1/5 from each side

W = 7 1/3 - 1/5

get a common denominator of 15

W= 7 1/3*5/5 - 1/5 *3/3

W = 7 5/15 - 3/15

W = 7 2/15
