Question
While making pastries, a bakery used 2/5 of a bag of wheat flour and 1/2 of a bag 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 2/5 of a bag of wheat flour and 1/2 of a bag of white flour.
To find out how many bags of flour the bakery used in total, you need to add these two fractions together.
Before you can add fractions, they must have the same denominator. In this case, the denominators are 5 and 2. The least common multiple of 5 and 2 is 10.
So, you need to convert each fraction to an equivalent fraction with a denominator of 10:
2/5 = 4/10 1/2 = 5/10
Now you can add the fractions:
4/10 + 5/10 = 9/10
So, the bakery used 9/10 of a bag of flour in total.
