Question

which ratio is Greater in each of the following pairs of ratios (a) 5:6 or 7:9​

Answer 1

Answer:

5:6 is greater than 7:9.

Step-by-step explanation:

7:9 = 0.77777777 repeating

5:6 = 0.83333333 repeating

You can see that 0.83 is greater than 0.77.

7:9 and 5:6 can have the same denominator of 54.

7:9 (multiply the top and bottom by 6) to get 42:54

5:6 (multiply the top and bottom by 9) to get 45:9

Now, you can look only at the numerators, 42 and 45. 45 is greater, so 5:6 is greater than 7:9.

Answer 2

5:6 is greater than 7:9
