Answer 1

Hi,

Here is the solution...

We convert this fraction into percentage.

To convert the fraction into percentage, we need to multiply the fraction by 100.

Math test score =
`(21)/(23) *100 = (2100)/(23) = 91.30`%

Science test score =
`(29)/(32) *100 = (2900)/(32) = 90.63`%

Now you can compare the percentage.

Julie scored higher in Math test.

Hope you will understand the steps.

Thank you. :)
