How to subtract mixed numbers with unlike denominators?

First, determine if you can turn the mixed number into a fraction. A great way to do this is with a fraction bar. Translate your mixed number into a fraction by lining up the denominator with the numerator. If the denominator is larger than the numerator, reduce it to the denominator by dropping the excess digits from the top. If the denominator is smaller than the numerator, add the denominator to the numerator and reduce the resulting sum by dropping the excess digits

Subtract mixed numbers with unlike denominators?

If you were to subtract 1 from the first number in the example, you would get an answer of -15. You could see that the denominator of the second number is -15 and that is what makes the answer -15 when you subtract them together. To subtract these two numbers, you need to figure out which fraction is the denominator of the first number. You can do this by multiplying the first number by its denominator. The result is -1. To subtract -1 from -

How do you subtract mixed numbers with unlike denominators?

If you have two different denominators, subtract them with a calculator. If you have more than two different denominators, you can use a calculator or a spreadsheet. If you do not have access to a calculator, use a piece of lined paper. You can use the grid method to subtract the smaller from the larger number, or the cross method.

How to subtract mixed-number equations with unlike denominators?

To subtract mixed numbers with unlike denominators, you need to make sure your equation is equivalent to the formula the problem gives you. If you have an equation with two variables with different denominators, then you need to find a way to make the denominators the same using multiplication, division, or a fraction. If that’s not possible, you need to convert to a different equation. There are many ways to convert to a different equation, but the two most common are to use the reciprocal

Subtract mixed numbers with unlike denominators word problem?

A class of mixed numbers has like denominators and unlike denominators. If one of the denominators is bigger than the other, the problem is called an improper fraction. If the two denominators are the same, the fraction is called a mixed number. If you add or subtract two improper fractions with unlike denominators, you get an improper fraction with a different denominator. To subtract two improper fractions with unlike denominators, you need to first make the denominators the same.
