Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The divisor of a fraction - the bottom number in a fraction - the part of a fraction below the line - which tells how many equal parts there are in the whole or in the group.
