Subtracting Fractions: 1 1/2 Cups Minus 2/3 Cup
Let's solve the problem of subtracting 2/3 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 * 2 = 2
- Add the numerator of the fraction (1): 2 + 1 = 3
- Keep the same denominator (2): 3/2
Now we have the problem: 3/2 - 2/3
Finding a Common Denominator
To subtract fractions, they must have the same denominator. The least common denominator of 2 and 3 is 6.
- Multiply 3/2 by 3/3 (which is equal to 1): (3/2) * (3/3) = 9/6
- Multiply 2/3 by 2/2 (which is equal to 1): (2/3) * (2/2) = 4/6
Our new problem is: 9/6 - 4/6
Subtracting Fractions
Now that the fractions have the same denominator, we can simply subtract the numerators:
- 9/6 - 4/6 = 5/6
Answer
Therefore, 1 1/2 cups minus 2/3 cup equals 5/6 cup.
