Answer:

There were 120 questions on the test.

Explanation:

It is given that:

Number of questions answered = 54

Grade percent = 45%

Let,

x be the total number of questions

45% of x = 54

$(45)/(100)x=54\\0.45x = 54$

Dividing both sides by 0.45

$(0.45x)/(0.45)=(54)/(0.45)\\x=120$

Therefore,

There were 120 questions on the test.
