Ratios Please help
The ratio of 5 3/5 to 2 1/10
The ratio of 7 dimes to 3 quarters
Marc took 3 hours(h)to mow a lawn while Angelina took 150 minutes (min) to mow the same lawn a week earlier. Write the ratio of Marc's time to Angelina's time as a ratio of whole numbers.

Math 
Kelly,
The ratio of 7 dimes to 3 quarters= 70 and 75 common factor of 5. So I can divide both numbers by 5 to get a ratio that means exactly the same thing as 70 to 75. This ratio will be 14 to 15

Math 
Allison,
Can you show me how you did this problem please.

Math 
Ms. Sue,
5 3/5 divided by 2 1/10 =
28/5 / 21/10 = 28/5 * 10/21 = 280/105 = 2 2/3 to 1
If you post your answers to the other two questions, we'll be glad to check them. 
Math
