While making pastries, a bakery used 1/2 of a bag of wheat flour and 4 bags of white flour. How many bags of flour did the bakery use in all?Write your answer as a fraction or as a whole or mixed number.
Solution
The bakery used 1/2 bag of wheat flour and 4 bags of white flour.
Step 1: Convert the whole number to a fraction. 4 bags of white flour is the same as 4/1 bags of white flour.
Step 2: Add the fractions. 1/2 (wheat flour) + 4/1 (white flour) = 1/2 + 8/2 = 9/2 bags of flour.
Step 3: Convert the improper fraction to a mixed number. 9/2 is the same as 4 1/2.
So, the bakery used 4 1/2 bags of flour in total.
