How to add and subtract fractions with different denominators and whole numbers?

It’s important to understand that when you add or subtract fractions, you need to consider the denominators For example, if you have of a pie and of a cake, you can add these two fractions together. However, if you have of a cake and of a pie, you need to express the in terms of the denominator of the smaller fraction (the denominator of the cake) before adding it to the larger fraction. So, you’d

How to add and subtract fractions with mixed denominators and whole numbers?

This type of problem is very similar to the one discussed previously. The only difference is that you have mixed whole numbers and fraction denominators This problem could be made easier by placing the whole numbers on top, so you can see the denominators.

How to add and subtract fractions without calculator?

One of the most difficult things about learning fractions is working with numbers that have different denominators, like 9 and 12. You can actually do a lot of mental gymnastics to add or subtract these numbers without a calculator. Luckily, it is very easy to learn strategies that will make adding and subtracting fractions a breeze. To learn how to add and subtract fractions without a calculator, start by trying to find common denominators for the fractions you are working with.

How to subtract fractions with the same denominator?

To subtract one fraction from another, subtract the numerator of the second fraction from the denominator of the first fraction. If the denominator of one fraction is larger than the other, the answer will be a negative number. If the denominator of one fraction is smaller than the other, the answer will be a positive number.

How to add and subtract fractions with mixed denominators?

In order to add or subtract two mixed denominator fractions, the denominators must be multiples of one another. If the denominators are not multiples of one another, the resulting fraction will have a remainder and will not be an answer to your question. For example, consider the following fraction: The denominator of the mixed denominator fraction is 12 and the denominator of the fraction you are adding is 20. You can check that the denominators are multiples of one another.
