What is 7 1/4 minus 3 3/8?
You need a common denominator to subtract fractions.
7 1/4 = 7 2/8 = 6 10/8
6 10/8 - 3 3/8 = 3 7/8
7 1/4 = 29/4 = 58/8
3 3/8 = 27/8
58/8 - 27/8 = 31/8 = 3 7/8
change the fractions to all over 8ths. for instance 7*8 is 56+(1/4)= 58/8
now do the same for 3 3/8th
To answer this question, you need to subtract the given numbers. Let's start by converting the mixed numbers into improper fractions for easier calculations.
First, we convert 7 1/4 into an improper fraction:
To do this, multiply the whole number (7) by the denominator (4) and add the numerator (1). This gives us: 7 x 4 + 1 = 29.
So, 7 1/4 is equivalent to 29/4.
Next, we convert 3 3/8 into an improper fraction:
Following the same process, we get: 3 x 8 + 3 = 27.
Therefore, 3 3/8 is equal to 27/8.
Now that both numbers are in improper fraction form, we can subtract them:
29/4 - 27/8
To subtract fractions, we need a common denominator. In this case, the smallest number that both 4 and 8 can both divide evenly into is 8.
Now, let's convert 29/4 to an equivalent fraction with 8 as the denominator:
To get 8 in the denominator, we multiply both the numerator and denominator of 29/4 by 2:
(29 x 2) / (4 x 2) = 58/8
Our equation becomes:
58/8 - 27/8
Now that the fractions have the same denominator, we can simply subtract the numerators while keeping the denominator the same:
58/8 - 27/8 = (58 - 27) / 8 = 31/8.
Therefore, 7 1/4 minus 3 3/8 equals 31/8.
