4 1/3 - 1 1/4 = 2 3/12?
Change to common denominator.
52/12 - 15/12 = 37/12 = 3 1/12
Is my equation above right?
My answer for my problem is 2 13/12
2 13/12 = 3 1/12
To solve this arithmetic problem, we need to subtract the two given mixed numbers: 4 1/3 - 1 1/4.
Step 1: Convert the mixed numbers into improper fractions.
4 1/3 can be written as (4 * 3 + 1) / 3 = 13/3.
1 1/4 can be written as (1 * 4 + 1) / 4 = 5/4.
Step 2: Find a common denominator for the fractions. In this case, the common denominator is 12, which is the least common multiple of 3 and 4.
Step 3: Convert the fractions into fractions with a common denominator.
13/3 can be written as (13 * 4) / (3 * 4) = 52/12.
5/4 can be written as (5 * 3) / (4 * 3) = 15/12.
Now, we have:
52/12 - 15/12.
Step 4: Subtract the numerators while keeping the common denominator.
52/12 - 15/12 = (52 - 15) / 12 = 37/12.
Therefore, the correct answer is not 2 3/12, but it is actually 3 1/12.
To check our solution, we can convert 3 1/12 back into a mixed number: 3 1/12 = (3 * 12 + 1) / 12 = 37/12.
So, the solution is 3 1/12.
