How would I do this? Do I need to get them into the sames type of money like pennies? I am lost!

7 dimes to 3 quaters??

they were probably asking for the ratio of 7 dimes to 3 quarters.
which is 70 cents:75 cents
which is 14:15 as a ration of "value"

5/6- 1/6

2 litres:1000 litres

To find the ratio of 7 dimes to 3 quarters, you need to compare the value of the dimes to the value of the quarters.

First, we need to know the value of each coin. A dime is worth 10 cents, and a quarter is worth 25 cents.

Since we want to compare the values of the dimes and quarters, we need to express them in the same unit. In this case, we can use cents. So, 7 dimes would be equal to 7 x 10 = 70 cents, and 3 quarters would be equal to 3 x 25 = 75 cents.

Now we have the values in cents: 70 cents for the dimes and 75 cents for the quarters.

To express the ratio, we divide both values by their greatest common divisor to simplify it. In this case, the greatest common divisor of 70 and 75 is 5. So, we divide 70 by 5 and 75 by 5:

70 / 5 = 14
75 / 5 = 15

Therefore, the ratio of 7 dimes to 3 quarters is 14:15.
