- This question is solved by proportions, using a rule of three.
- Each tile uses 1/2 = 0.5 ft.
- In total, he needs 2 ft.
Thus, the<u> rule of three</u> is given by:
1 tile - 0.5 ft
x tiles - 2 ft
Applying cross multiplication:

Answer:
17
Step-by-step explanation:
1037 divided by 61. First, 63 can't go into 1 or 10. So it would go into 103. If you multiply 61 twice, it's more than 103. so just subtract 61 from 103. 103 - 63 = 42. Bring down the 7. now you have 427. If you multiply 61 by 7, you get 427. 427-427 = 0. You are left with the answer 17.
