TSI Practice Test: Video 1 Answers (25 Questions)

Question 1

What is 3/4 + 1/8?

Accepted Answer

7/8

Answer

Convert 3/4 to 6/8, then add 1/8 to get 7/8. Adding the numerators and denominators directly (4/12) is the common mistake.

Question 2

What is 20% of 150?

Accepted Answer

30

Answer

One fifth of 150 is 30. 25 would be about 16.7 percent.

Question 3

What is 0.6 × 0.5?

Accepted Answer

0.3

Answer

6 × 5 = 30, with two decimal places gives 0.30. 0.11 comes from adding instead of multiplying.

Question 4

A car travels 180 miles in 3 hours. At the same rate, how far in 5 hours?

Accepted Answer

300 miles

Answer

The rate is 60 mph, so 5 hours gives 300 miles. 360 would be 6 hours.

Question 5

A jacket costs $80 and is discounted 25%. What is the sale price?

Accepted Answer

$60

Answer

25% of 80 is 20, so the price is $60. $55 subtracts 25 dollars instead of 25 percent.
