If you have common denominators, then you subtract the numerators of the fraction in the same way you do any other numbers. So yes you can borrow.

How are equivalent fractions used in renaming when subtracting?

When subtracting one fraction to another, one or both fractions are renamed so that they have the same denominators. Then the result of the subtraction is the equal to the subtraction of the numerators divided by the common denominator.


How do you solve a fraction problem when you don't have the same denominator?

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


What do you do to a fraction before adding subtracting or dividing?

When adding or subtracting, convert all fractions in the question to a common denominator/ 1/2 + 1/4 - 1/3 = 6/12 + 3/12 - 4/12 = 5/12


How can knowing the GCF and LCM help you when you add subtract and multiply fractions?

Knowing the LCM will help when adding or subtracting unlike fractions. By finding the LCM of the denominators, (called the lowest common denominator) you can convert unlike to like fractions and proceed with the adding or subtracting. Knowing the GCF helps reduce a fraction. By finding the GCF of the numerator and the denominator and dividing both of them by it, you can reduce a fraction to its lowest terms (simplest form). If the GCF is 1, the fraction is in its simplest form. You can successfully multiply fractions without knowing the GCF or LCM.


What is 1.77777777777 as a fraction?

To convert the repeating decimal 1.77777777777 to a fraction, we can set it as x = 1.77777777777. To eliminate the repeating decimal, we multiply x by 10 to get 10x = 17.7777777777. Subtracting x from 10x gives 9x = 16, so x = 16/9. Therefore, 1.77777777777 as a fraction is 16/9.
