Answer:
8. 8:10 - 4:5
9. 9:12 - 3:4
10. 15:40 - 3:8
V.
11. N:8 - 12:32 ➡️ 3:8 - 12:32
12. 5:3 - 25:N ➡️ 5:3 - 25:15
13. 3:N - 4:36 ➡️ 3:35 - 4:36
Step-by-step explanation:
Get the least common factor of both number
8. In this case, 8:10 divide both with 2 to simplify the ratios into 4:5
9. 9:12, their both LCF is 3 so divide it both to get the result 3:4
10. 15:40 should be divided both with 5 to simplify it to 3:8.
11. Again get the LCF of 12 and 32 which is 4 and then divide it to the 12 to get the N.
12. To get the N, divide 25 to 5 then the result is 5 which is the LCF of 25 and the N so simply, multiply the 3 to 5 to get the N. The result is 25:15
13. In this item, I think you will simply minus 1 the 36 just like the 3 and 4
