Compare the two ratios is 6 : 15 less than 30 : 80 or greater than?

Work:
6/15 = x/1
To get from 15 to 1, you have to divide by 15. So, to make an equal field, divide 6 by 15.

6 : 15 is the same as 2 : 5 or 0.4.

30/80 = x/1
To get from 80 to 1, you have to divide by 80. So, to make an equal field, divide 30 by 80.

30 : 80 is the same as 3 : 8 or .875.

Comparing the two, 30 : 80 is greater than 6 : 15.

Hope this helps. Have a good day.
