Final answer:
Ronnie cuts sections of wood that are 3/5 of an inch long. Multiplying the length of one section (0.6 inches) by the number of sections (35) gives us a total of 21 inches.
Step-by-step explanation:
Ronnie cuts 3 over 5-inch sections of wood to make a birdhouse roof. He cut 35 of these sections. To find out how many inches of wood he cut in total, we need to multiply the length of one section by the number of sections.
Firstly, convert 3 over 5 into a decimal, which is 0.6 inches. Then, multiply 0.6 inches by the total number of sections, which is 35:
- 0.6 inches/section * 35 sections = 21 inches
Therefore, Ronnie cut a total of 21 inches of wood for the birdhouse roof.
