1 1/2 Minus 3/4 as a Fraction
This article will guide you through the process of subtracting 3/4 from 1 1/2, resulting in a fraction.
Step 1: Convert Mixed Number to a Fraction
The first step is to convert the mixed number, 1 1/2, into a fraction. To do this, we multiply the whole number (1) by the denominator of the fraction (2) and then add the numerator (1). This result becomes the new numerator, and the denominator stays the same.
1 1/2 = (1 * 2 + 1)/2 = 3/2
Step 2: Find a Common Denominator
Now, we have 3/2 - 3/4. We need to find a common denominator for both fractions. The least common multiple of 2 and 4 is 4.
To change 3/2 to a fraction with a denominator of 4, we multiply both the numerator and denominator by 2:
(3 * 2)/(2 * 2) = 6/4
Step 3: Subtract the Fractions
Now we can subtract the fractions:
6/4 - 3/4 = (6 - 3)/4
Step 4: Simplify the Result
Finally, we simplify the result:
(6 - 3)/4 = 3/4
Therefore, 1 1/2 minus 3/4 is 3/4.
