Question

Please help me with this math assignment

Answer 1

80%

210%

65%

105%

Explanation:

To solve for each of these equations, let's make them fractions first. The denominator will be 20 since that was the goal.

Elena did
`(16)/(20)` pushps.

Jada did
`(42)/(20\\)` pushups.

Lin did
`(13)/(20)` pushups.

Andre did
`(21)/(20)` pushups.

To convert this to percentages, let's multiply each by fraction by
`(5)/(5)`. This will give us a denominator of 100. The denominator will represent the percentage.

Elena did
`(16)/(20)` ×
`(5)/(5)` =
`(80)/(100)` pushps. Elena did 80 percent of the pushups.

Jada did
`(42)/(20\\)` ×
`(5)/(5)` =
`(210)/(100)` pushups. Jada did 210 percent of the pushups.

Lin did
`(13)/(20)` ×
`(5)/(5)` =
`(65)/(100)` pushups. Lin did 65 percent of the pushups.

Andre did
`(21)/(20)` ×
`(5)/(5)` =
`(105)/(100)` pushups. Andre did 105 percent of the pushups.
