Question

Joanne signed up for 24 dancing lessons she took 3/4 of the by April and 1/5 of them by May .What part of dancing lesson did she take?

Answer 1

`Part = (19)/(20)`

`Lessons = 23`

Explanation:

Given:

`Dancing\ Lessons = 24`

`April = (3)/(4)`

`May = (1)/(5)`

Required:

Determine the part she took

To solve this, we simply add up the part she took in April and May.

`Part = (3)/(4) + (1)/(5)`

Take LCM

`Part = (15 + 4)/(20)`

`Part = (19)/(20)`

Hence, she took
`(19)/(20)` of the dancing lesson.

However, to calculate the number of lesson.

We have to multiply
`(19)/(20)` by the total dancing lessons.

`Lessons = (19)/(20) * 24`

`Lessons = (19* 24)/(20)`

`Lessons = (456)/(20)`

`Lessons = 22.8`

`Lessons = 23` ---- Approximated
