Yes, you multiply the numerator by the numerator, and the denominator by the denominator, and then reduce the fraction. For instance:
One half of two fifths is
1/2 x 2/5 = 2/10 which, when reduced, equals 1/5. Logically, if you have half of two fifths, you have one fifth. If you had half of four fifths, you would have two fifths, and so on.
No.
You DO need a common denominator to add, subtract, or compare fractions. You DO NOT need a common denominator to multiply or divide fractions.
YES.
yes
No.
No.
yes. you multiply the numerator and denominator
Change the fractions to the same denominator then compare.A quick way is to multiply UP on cross multiply and compare.
multiply denominator by denominator and vice versa
Multiply the numerator and the denominator by the same integer.
Yes you do.
Divide the denominator into the numerator. Multiply the result by 100.
No.
you do not do that
None. Multiply numerator by the numerator and denominator by denominator.
Multiply the denominator by the whole number, add the numerator and put that total over the denominator.
First, find a common denominator for the two (or more) fractions. Then, for each fraction, multiply numerator and denominator by the same number (different numbers for different fractions, though), to convert to the common denominator.
