1 1/2 Cups Minus 3/4: A Step-by-Step Guide
This article will guide you through the process of subtracting 3/4 from 1 1/2 cups.
Understanding the Problem
We need to subtract 3/4 of a cup from 1 1/2 cups.
Converting Mixed Numbers to Fractions
First, we need to convert the mixed number 1 1/2 into an improper fraction.
- Multiply the whole number (1) by the denominator of the fraction (2): 1 x 2 = 2
- Add the numerator of the fraction (1): 2 + 1 = 3
- Keep the same denominator: 3/2
Now, our problem becomes: 3/2 - 3/4
Finding a Common Denominator
To subtract fractions, they must have the same denominator. The least common denominator for 2 and 4 is 4.
- To convert 3/2 to a fraction with a denominator of 4, multiply both the numerator and denominator by 2: (3 x 2) / (2 x 2) = 6/4
Our problem now looks like this: 6/4 - 3/4
Subtracting the Fractions
Now that both fractions have the same denominator, we can subtract the numerators.
- 6/4 - 3/4 = 3/4
The Answer
1 1/2 cups minus 3/4 cup equals 3/4 cup.
