Answer:
7. 58 minutes
8. 89
Explanation:
7. To solve this problem add up all the minutes Kinza jogged on Mon., Tues., Wed., and Thursday.
16 + 13 + 9 + 20 = 58
She jogged 58 minutes in total.
8. One strategy to add 16 + 35 + 24 + 14 is to round them to the nearest tenth like so.
20 + 40 + 20 + 10 = 90
Since all the numbers were one 4 away from their rounded number besides 35, you would just subtract 1 from the final answer (because you rounded UP 1 more).
90 - 1 = 89
Another strategy is to add 16 and 24 together using mental math, which is 40. Then you could add 35 and 14 together, which is 49.
Add up 40 and 49 to get the same answer of 89.
