Subtracting Mixed Numbers: 1 1/3 minus 1 1/4
In this article, we will subtract 1 1/4 from 1 1/3. To do this, we need to follow the steps for subtracting mixed numbers.
Step 1: Convert to Improper Fractions
Before we can subtract, we need to convert our mixed numbers to improper fractions.
1 1/3 = ? To convert 1 1/3, we multiply the whole number part (1) by the denominator (3) and then add the numerator (1).
1 × 3 + 1 = 4 So, 1 1/3 = 4/3.
1 1/4 = ? To convert 1 1/4, we multiply the whole number part (1) by the denominator (4) and then add the numerator (1).
1 × 4 + 1 = 5 So, 1 1/4 = 5/4.
Step 2: Subtract the Fractions
Now that we have our improper fractions, we can subtract them.
4/3 - 5/4 = ? To subtract these fractions, we need a common denominator. The least common multiple of 3 and 4 is 12. So, we will convert both fractions to have a denominator of 12.
4/3 = 16/12 5/4 = 15/12
Now we can subtract:
16/12 - 15/12 = 1/12
The Answer
So, 1 1/3 minus 1 1/4 is equal to 1/12.
