Step-by-step explanation:
1 part of 3 sections of a wall takes 1/4 of an hour, (.25 or 25% of an hour), (15 minutes is 1/4 of 60 minutes), so if it takes 15 minutes for one section to be painted & you have 3 sections,
(15+15+15) or (15×3)
= your answer
First, find the number in the 10 thousands place. In 1,346,935, 4 is in the 10 thousands place. 6 is next to 4, and is larger than 5, so round 40 thousand to 50 thousand. The answer is 1,350,000.
