Answer:
8
4 --
11
Step-by-step explanation:
The gear ratio for the original gear system was 4/22. To get the 22 inch wheel to 26 inches, you have to multiply it by 26/22, so to keep the same ratio, you will also need to multiply 4 by 26/22. You get 104/22, which simplifies to 52/11 which simplified further to 4+8/11. You can check your answer by comparing the original ratio to the new ratio.
Answer:
1/4
Step-by-step explanation:
2/3 * 4/4 = 8/12
8/12 + 1/12 = 9/12
12/12 - 9/12 = 3/12
3/12 simplified is 1/4
