Final answer:
To solve the equation 1 3/4 + 1/6 + ____ = 7 1/2, you need to find the missing number that, when added to 1 3/4 + 1/6, equals 7 1/2. By converting the fractions to have a common denominator of 12, you can find the sum of 7/4 and 1/6, subtract that from 7 1/2, and determine that the missing number is 1/3.
Step-by-step explanation:
To solve the equation 1 3/4 + 1/6 + ____ = 7 1/2, we need to find the missing number that when added to 1 3/4 + 1/6 equals 7 1/2.
To find the missing number, we can convert all the fractions to have the same denominator. The least common denominator between 4 and 6 is 12.
Converting 1 3/4 to an improper fraction gives us 7/4, and converting 1/6 to an improper fraction gives us 1/6. So, the equation becomes:
7/4 + 1/6 + ____ = 7 1/2.
Next, we find the sum of 7/4 and 1/6: 7/4 + 1/6 = 42/24 + 4/24 = 46/24.
Now, we subtract 46/24 from 7 1/2 to find the missing number: 7 1/2 - 46/24 = (54/2 - 46/24) = 27 - 46/24 = 27/1 - 46/24 = 54/2 - 46/24 = 8/24 = 1/3.
So, the missing number is 1/3, and the completed equation is: 7/4 + 1/6 + 1/3 = 7 1/2.
