Question

nick removed 3/5 of the snow from the lawn yesterday and 1/4 of the lawn this morning. how much is left to remove

Answer 1

Answer: 4/20

Step-by-step explanation: you need to make the denominator the same to solve so you would do 3/5 × 4 and get 12/20 then 1/5 × 5 and get 4/20 add em up and get 16/20 now you just add to the numerator until you get 1

Answer 2

For this case, we have to know if Nick removed
`\frac {3} {5}` from the snow on the grass yesterday, then it remains:

`\frac {5} {5} - \frac {3} {5} = \frac {2} {5} \ of \ snow`

If from those
`\frac {2} {5}`then removed
`\frac {1} {4}` this morning, then it remains:

`\frac {2} {5} - \frac {1} {4} = \frac {4 * 2-5 * 1} {20} = \frac {3} {20}`

Thus, it remains to remove
`\frac {3} {20}`of snow.

Answer:

`\frac {3} {20}`
