5 x 3 = 15because if you have 3 groups of 5 gummy bears and you count all of them (add) the answer will be 15 gummy bears . And no, the answer wouldn't be different if it was 3 x 5 =.
No, it is not. If you multiply 3 by 4, you get 12. However, you must multiply 5 by 5 to get 25, so it is not equivalent.
You don't multiply by the second number, you multiply by the recipricol. For example, 5/8 divided by 3/5... you multiply 5/8 by 5/3. Which would give you 25/24ths, or 1 and 1/24.

You don't need a common denominator to multiply or divide fractions.To multiply fractions, multiply the numerators and the denominators, e.g.:1/2 x 3/5 = (1/3) / (2/5) = 3/10To divide fractions, multiply the first fraction with the reciprocal of the second.1/2 divided by 5/3 is the same as 1/2 times 3/5.

105First multiply 1 and 3 to get 3. Second multiply 3 and 5 to get 15. Third multiply 15 and 7 to get 105.
