How To Use Fractions In 4-Operations

Addition:

To add fractions, make sure the denominators are the same. Add the numerators together and keep the denominator the same. Simplify the result if needed.

Subtraction:

Similar to addition, ensure the denominators are identical. Subtract the numerators while keeping the denominator constant. Simplify the result if necessary.

Multiplication:

Multiply the numerators together to get the new numerator. Multiply the denominators together to get the new denominator. Simplify the resulting fraction if possible.

Division:

To divide fractions, multiply by the reciprocal of the second fraction. Invert the second fraction (swap the numerator and denominator). Then, follow the steps for multiplication.
