Question

Tiffany used to live 15 kilometers away from the school, but after she moved she now lives 9.9 kilometers away. She is _____ percent closer to the school.

Answer 1

Tiffany is 34% closer to the school.

Explanation:

Given the statement: Tiffany used to live 15 kilometers away from the school, but after she moved she now lives 9.9 kilometers away.

She lived away from the school = 15 km

as, she moved 9.9 km away.

Now, the distance closer to school from where she lived = 15 -9.9 = 5.1 km

To, find how much percent she is closer to school.

Percent states that a number or ratio expressed as a fraction of 100.

`percent = (5.1)/(15) * 100` =
`(51 * 100)/(150) = (51 * 10)/(15)`

Simplify:

percent closer to school = 34%

Therefore, she is 34% closer to the school.
