Question

Do you have to turn it into a mixed number?

Community Answer

No, the answer is correct without turning it into a mixed number. It's just that mixed numbers are often more easily grasped than the equivalent improper fractions.

First find common denominators. The least common denominator is 10. Multiply 1/2 by 5/5 to get 5/10. Then multiply 1/5 by 2/2 to get 2/10. 25 5/10 + 18 2/10 = 43 7/10. Your answer is 43 7/10.

Question

How do you multiply a whole number by a fraction?

Community Answer

Multiply the whole number by the numerator and keep the denominator the same. Simplify and/or convert to a mixed number if desired. For example: 12 x 2/3 = 24/3 = 8.

Question

How do you add a whole number to a mixed number?

Community Answer

The easiest way is to add the whole number to the mixed number's whole number. Then add the fraction to the sum of the whole numbers. For example, 3 + 2½: add the 3 and the 2 to get 5. Then add the ½ to get 5½. Another way to do it is to convert both the whole number and the mixed number into improper fractions with the same denominator. Then add the numerators together and keep the denominator. To use the same example: 3 + 2½ = 6/2 + 5/2 = 11/2 = 5½.
