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. A/b / c/d = a/b x d/c - To divide a/b by c/d multiply by the reciprocal of c/d. - multiply by reciprocal of divisor - invert the second fraction and then multiply the fraction. - 1. do the reciprical of the second fraction 2. reduce if possible 3. m

2. If a - b - and c are any numbers - then a/b = ac/bc if b doesn't = 0 and c doesn't = 0 And a/b =a/c/b/c if b doesn't = 0 and c doesn't = 0

3. The reciprocal of a/b is b/a.
Mixed number
Subtraction of fractions
Reducing to lowest terms
Reciprocal of a fraction
4. A/b + c/b = a+c / b - Two fractions with the same denominator can be added or subtracted by performing the required operation with the numerators - leaving the denominators the same. For example - -and . If two fractions do not have the same denomin

5. A fraction is reduced to lowest terms when there are no common factors (except 1) in the numerator and denominator - To reduce a fraction to lowest terms - you have to find a common factor that both the numerator and denominator go into - the smalles
