No because the numerator and the denominator must be multiplied or divided by the same number for a given equivalent fraction

by multiplying the denominator with the whole number and adding the numerator. the denominator will remain the same.

If you are adding or subtracting unlike fractions, convert them to equivalent fractions with a common denominator.

yes

Yes, you must convert both fractions to the same denominator to add them. Now... Do the rest of your homework yourself!

The denominator should be the same as the denominator of the fraction.

Same as for adding: If the denominators are not equal, you must first find a common denominator, then convert both fractions to that common denominator.

No.

Simply change the numerator and you will have another - different - fraction wit the same denominator.

That depends on the other denominator. You need at least two.

When the numerators are the same, the fraction with the higher denominator is less than the fraction with the lower denominator. The denominator indicates the size of the "parts" being shown as a fraction, and the higher the denominator, the smaller those parts are!

Any fraction with the same numerator and denominator is equal to ' 1 '.

If the numerator and denominator are the same, the fraction simplifies to 1. And you should be able to subtract 1!

What is a fraction in which the numerator and denominator represent the same amount but are in different units?

A fraction is equivalent to another if the ratio of the numerator and denominator is the the same in both. To find an equivalent fraction, multiply or divide the numerator and denominator by the same ammount.

Multiply the numerator of the fraction by the same amount that you multiply the denominator of that fraction.

If both the numerator AND denominator are the same... the fraction is an equivalent for the number 1

The one where the denominator is the same and the numerator is the whole number multiplied by the denominator plus the numerator of the fraction.

The numerator of the answer is the result of subtracting the numerators of the fractions, and the denominator of the fraction is the same as the common denominator.

That's an improper fraction.
