Subtract fractions and decimals practice. What is eight -7 1/4
To subtract mixed numbers, you first need to convert the mixed number into an improper fraction.
For the mixed number 7 1/4, the improper fraction is (7 * 4 + 1)/4 = 29/4.
Now, the subtraction becomes 8 - 29/4.
To subtract fractions, you need to have a common denominator. The common denominator in this case is 4.
Now, rewrite 8 as a fraction with a denominator of 4:
8 = 8/1 = 32/4.
Subtracting the fractions gives:
32/4 - 29/4 = (32 - 29)/4 = 3/4.
Therefore, eight minus 7 1/4 is equal to 3/4.
To subtract fractions and decimals, we need to convert the mixed number 7 1/4 into a fraction.
First, let's convert 7 into a fraction: 7 = 7/1
Then, we multiply the whole number, 7, by the denominator, 4, and add the numerator, 1:
7/1 * 4/4 = 28/4
Now we can subtract the fractions:
8 - 28/4 = 8/1 - 28/4
To subtract fractions with different denominators, we need to find a common denominator. In this case, the least common multiple (LCM) of 1 and 4 is 4.
Next, we need to multiply the numerator and denominator of each fraction to make the denominators equal to the LCM.
8/1 * 4/4 = 32/4
28/4
Now that the fractions have the same denominator, we can subtract them:
32/4 - 28/4 = (32 - 28) / 4 = 4/4
Simplifying 4/4, we get:
4/4 = 1
Therefore, 8 - 7 1/4 equals 1.
