You just multiply the numerator of the first fraction by the numerator of the second, and the denominator of the first by the denominator of the second. For example, with the two fractions 2/9 and 4/7, you would multiply 2 by 4 to get 8, then 9 by 7 to get 63, so your answer to 2/9 x 4/7 would be 8/63.

Fractions with different denominators are called?
unlike fractions
What are Fractions that have different denominators?
unlike fractions
What way is subracting fractions with unlike denominators like adding fractions with unlike denominators?
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators.
When you add or subtract fractions with unlike denominators why do you have to find LCM?
Because to add fractions, the denominators must be equal.
What do you do when you mutpiling fractions with common dennmonters?
Exactly the same as you do when multiplying fractions with different denominators. -- Multiply numerators . . . the product is the numeratore of the answer. -- Multiply denominators . . . the product is the denominator of the answer.
