BabaBlast [244]

Answer:

Rhian did better in the Math test.  

Step-by-step explanation:

Given: Rhian scored 14 out of 17 in a Math test. In the English test she scored 31 out of 39.

To find: In which test did she do better?

Solution:

We have,

Rhian scored 14 out of 17 in a Math test.

Rhian scored 31 out of 39 in an English test.

So, first we need to find the percentage of the marks scored.

Percentage in the Math test =\frac{14}{17}\times100=82.35 \%.

Percentage in the English test =\frac{31}{39}\times100= 79.49\%.    

Clearly, the percentage in the Math test is greater than the percentage in the English test.

So, Rhian did better in the Math test.
