## How do you add fractions with unlike denominators on a calculator?

When the Denominators are Unlike or Different We find the Least Common Denominator (LCD) then rewrite all fractions in the equation as equivalent fractions using the LCD as the denominator. When all denominators are alike, simply add or subtract the numerators and place the result over the common denominator.

**How do u add fractions with unlike denominators?**

Here’s the traditional way to add fractions with two different denominators:

- Find the LCM of the two denominators. Suppose you want to add the fractions 3/4 + 7/10.
- Increase the terms of each fraction so that the denominator of each equals the LCM.
- Substitute these two new fractions for the original ones and add.

**How do you add and subtract fractions with unlike denominators and whole numbers?**

Step 1: Find the Lowest Common Multiple (LCM) between the denominators. Step 2: Multiply the numerator and denominator of each fraction by a number so that they have the LCM as their new denominator. Step 3: Add or subtract the numerators and keep the denominator the same.

### How do you add and subtract like fractions?

Like fractions are fractions with the same denominator. You can add and subtract like fractions easily – simply add or subtract the numerators and write the sum over the common denominator.

**How do you convert fraction into simplest form?**

A fraction is in simplest form when the top and bottom cannot be any smaller, while still being whole numbers. To simplify a fraction: divide the top and bottom by the greatest number that will divide both numbers exactly (they must stay whole numbers).

**What are the rules for subtracting fractions?**

Remember the following rules when subtracting fractions: Rule #1: Never add denominators. Rule #2: Subtract only the numerators. Rule #3: Subtract the numerators only and only if the denominators are the same.

#### How do you subtract a whole number with a fraction?

Subtracting fractions from whole numbers isn’t as hard as it looks. There are two main ways to go about it: you can either convert the whole number into a fraction, or subtract 1 from that whole number and convert the 1 into a fraction with the same base as the fraction you’re subtracting from it.
