Question

Erin received the following scores on her last four spelling tests.21\25, 82%, 0. 8, 17\20.

Which of these is Erin’s highest score?

Answer 1

`\huge\boxed{(17)/(20)}`

We will convert each of the scores to a percentage.

`(21)/(25)*(4)/(4)\to(21*4)/(25*4)\to(84)/(100)\to84\%`

`82\%`

`0.8*100\to80\%`

`\boxed{(17)/(20)}*(5)/(5)\to(85)/(100)\to\boxed{85\%}`

So, the answer is the last option.

Answer 2

The highest score is the last one 17/20

Explanation:

Step 1: Convert all to percentage

21/25 -> 0.84 * 100 -> 84%

82%

0.8 * 100 -> 80%

17/20 -> 0.85 * 100 -> 85%

Answer: The highest score is the last one 17/20
