The ratio of dogs to cats is 5:3 ,the ratio of fish to dogs is 6:1 .what is the ratio of cats to fish

10: 1

Step-by-step explanation:

We have to make the dogs art of the ratio equal first.

5:3>30:18

6:1> 180: 30

After this we have to simplify the ratio.

Cats to fish is 180:18 (divide by 2) 90:9 (then by 3) 30 : 3 (and finally by 3 again) 10 : 1

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
