Question

bianca and yoko work together to mow the lawn. suppose yoko mows 5/12 of the lawn and bianca mows 2/5 of he lawn. how.much lawn still needs to be mowed?

Answer 1

To start, we need to find a common denominator fraction that
`(5)/(12)` and
`(2)/(5)` could go into. This would be 60. Our fractions would be
`(25)/(60)` and
`(24)/(60)`. We add these together to get
`(49)/(60)`. To find how much still needs to be mowed, we do
`(60)/(60) - (49)/(60) = (11)/(60)`
