Answer:
Hi!
1.Well, let's try simplifying 4:18 so we can compare.
If we divide 4:18 by 2, we get 2:9
We can see that 2:9 =/= 2:12
Thus, the two are not equivalent ratios.
2. 5:20 and 15:60 are equivalent, 5:20 x 3 to both numbers is 15:60
Therefore, It is equivalent.
3. 17 times 4 is 68 and 3 times 4 is 12. 17:3 and 68:12 are equivalent because you can times and divide them into each other
4. He read for 180 minutes.
You can find that because every time he practices math for five minutes, he reads for 20, and 45 is 5, 9 times. So you multiply 20 by 9.
5. If he eats 3 slices in 2 minutes, he will have eaten 15 pieces in 10 minutes.
6. For this one, I hope my calculations are correct, but I do NOT think August made the correct recipe using the correct ratio.
If #6 is wrong, I sincerely Apologize, but I know for a fact #5 is Correct.
Hope this helps! If you need anymore help Let me know i'd be happy to help you!
