multiply denominator by denominator and vice versa

exactly you got it you dont need help :)

yes. you multiply the numerator and denominator

Multiply the numerator and the denominator by the same number or divide the numerator and the denominator by the same number

YES.

5/10 is equal to 1/2. Whatever you multiply the numerator by you must multiply the denominator and you will always get same valued fractions

Yes you do.

In order to add fractions, they must have the same denominators. If the fractions you wish to add do not already have the same denominators, they can be made to do so by finding the right number by which to multiply both the numerator and the denominator of each fraction. To find this number, multiply all the distinct denominators together, then multiply both the numerator and denominator of each fraction by a number found by the dividing the product of the distinct denominators by the denominator of the particular fraction concerned. All the fractions will then have the same denominator. Add the numerators of such fractions together to find the numerator of the sum; its denominator will be the one common to all the fractions.

Change the fractions to the same denominator then compare.A quick way is to multiply UP on cross multiply and compare.

Like fractions are the fractions which have the same denominator and unlike fractions are the fractions which do not have the same denominator.

Multiply the numerator and the denominator by the same number.

Multiply the numerator and the denominator by the same whole number.

Multiply the numerator and the denominator by the same integer.

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.

You multiply the denominator by the whole number the add the numerator and you keep the denominator the same.

It is easier to multiply or divide fractions than to add or subtract fractions because in multiplication, you just have to multiply the numerator by the numerator and the denominator by the denominator. Same applies with division of fractions, except that you have to reciprocate the fraction you're dividing with (divisor) then proceed to multiplication. Whereas, in addition and subtraction of fractions, you still have to get their Least Common Denominator (LCD).

Just multiply the two denominators of your fractions, the answer you get is a common denominator.

you do not do that

No.

No.

find a common denominator. multiply the top and bottom by it. then you can combine the numerators over the same denominator

Multiply both the numerator and the denominator by the same counting number.
