Question
At the Livingston Zoo's bug exhibit, Ellie watches a millipede crawl for 1/2 of a minute, stay still for a while, and then crawl for 4/5 of a minute more. How much total time did Ellie spend watching the millipede crawl?Write your answer as a fraction or as a whole or mixed number.
Solution
Ellie spent 1/2 of a minute and 4/5 of a minute watching the millipede crawl. To find the total time, we need to add these two fractions together.
Step 1: Find a common denominator. The least common multiple of 2 and 5 is 10. So, we will convert both fractions to have this common denominator.
1/2 = 5/10 4/5 = 8/10
Step 2: Add the two fractions together.
5/10 + 8/10 = 13/10
So, Ellie spent 13/10 of a minute watching the millipede crawl. This can also be written as 1 3/10 minutes.
