Answer 1

3/4

Explanation:

Maria practiced for her piano recital each day for three days. the first day she practiced for 3/4 hour, the second day she practiced for 1 1/2 hours, and the third day she practiced for 2 1/4 hours. by how much did she increase the time she practiced each day?

the increase in hours practiced can be determined by calculating the difference between the hours practiced on the second and first day

`1(1)/(2) - (3)/(4)`

`1(2 - 3)/(4)` the lowest common multiple that can divide 2 and 4 is 4.

`(6-3)/(4)` if 2 is subtracted from 3, the answer would be negative. So, borrow 1 from the whole number. the value of this borrowed one would be equal to 4 which is the LCM. Add 4 to 2. this gives 6

`(3)/(4)`
