On his english test he scored 67%
On his science test he scored 52%
On his math test he scored 63%
To calculate these you would divide by putting the amount of points he earned over the total possible points. Then convert the decimal to a percentage.
He scored the highest on his english test.

Explanation:

Convert each fraction by setting up proportion out of 100.


(60)/(90) = (?)/(100)


(78)/(150) = (?)/(100)


(75)/(120) = (x)/(100)

Cross multiply each fraction. let x represent the missing number.


6000 = 90x


7800 = 150x


7500 = 120x

Solve for x

For the first equation.


x = 66.66666

For the second equation


x = 52

For the third equation,


x = 62.5

Round each missing value to the nearest whole value and add the % sign.

60/90=67%

78/150=52%

75/120=63%

He scored the highest on his English test.
