Question

India can paint 3 1/5 walls in one day. How many walls can she paint in 5 1/2 days?

Answer 1

Change the mixed numbers into fractions.


`3 (1)/(5)`

`3 * 5 = 15`

`15 + 1 = 16`

`3 (1)/(5) = (16)/(5)`


`5 (1)/(2)`

`5 * 2 = 10`

`10 + 1 = 11`

`5 (1)/(2) = (11)/(2)`

Multiply these fractions together:


`(16)/(5) * (11)/(2) = (176)/(10)`

Simplify the fraction.


`(176)/(10) / (2)/(2) = (88)/(5)`


`88 / 5 = 17 R3 = 17 (3)/(5)`

India can paint 17 and 3/5 walls in 5 and a half days.
