What does flipping a fraction mean?
multiplicative inverse
Dividing fractions To divide one fraction by another one, flip numerator and denominator of the second one, and then multiply the two fractions. The flipped-over fraction is called the multiplicative inverse or reciprocal.
How do you simplify a fraction?
You can simplify a fraction if the numerator (top number) and denominator (bottom number) can both be divided by the same number. Six twelfths can be simplified to one half, or 1 over 2 because both numbers are divisible by 6.
How do you invert fractions?
To find the inverse of a fraction, switch the numerator and the denominator. If the fraction is a whole number, then it can be written as the whole number over 1, and its inverse is 1 over the whole number. Thus, to divide by a fraction, multiply by its inverse.

How do you add and simplify fractions?
To add fractions there are Three Simple Steps:
- Step 1: Make sure the bottom numbers (the denominators) are the same.
- Step 2: Add the top numbers (the numerators), put that answer over the denominator.
- Step 3: Simplify the fraction (if needed)
How do you add mixed numbers?
- To add mixed numbers, we first add the whole numbers together, and then the fractions.
- If the denominators of the fractions are different, then first find equivalent fractions with a common denominator before adding.
- Subtracting mixed numbers is very similar to adding them.
How do you invert in math?
The invert part of “invert and multiply” means to take the denominator of this big fraction, 1/4, and invert it. In other words, flip it on its head so its numerator becomes its denominator and vice versa. The inverse of 1/4 is therefore 4/1, or just 4.
When can you invert fractions?
To multiply two fractions, we multiply the numerators to get the new numerator and multiply the denominators to get the new denominator. However, we are taught that when faced with a problem such as 3⁄5 ÷ 4⁄7, we should invert the second fraction and multiply.
