Rhion sat maths and English test
Sauron [17]

Answer:

Rhion did better in maths test.

Step-by-step explanation:

Given that:

Rhion scored 14 out of 17.

We will find percentage and then compare them.

Percentage = \frac{Score}{Total\ marks}*100

Percentage = \frac{14}{17}*100

Percentage = 82.35%

Rhion scored 31 out of 39.

Percentage = \frac{31}{39}*100

Percentage = 79.48

On comparing,

82.35 > 79.48

Hence,

Rhion did better in maths test.
