*remember, you don't divide fractions, you multiply the first fraction by the inverse (flip it upside down) of the second fraction.*

(1/5) × (1/4) = (1/20)

Answer 2

`(1)/(20)` of weekend

Explanation:

We have been given that Tommy will spend 1/5 of his time this weekend studying for his 4 final exams. We are asked to amount of time spent on studying each subject.

To find the amount of time spent on studying each subject, we will divide time spent on all subjects by number of subjects.

`\text{Time spent on studying each subject}=(1)/(5)/ 4`

`\text{Time spent on studying each subject}=(1)/(5)/(4)/(1)`

Convert to multiplication problem:

`\text{Time spent on studying each subject}=(1)/(5)* (1)/(4)`

`\text{Time spent on studying each subject}=(1)/(5*4)`

`\text{Time spent on studying each subject}=(1)/(20)`

Therefore, Tommy spent
`(1)/(20)` of weekend on studying each subject.
