Question

which ratio is greater (5:6) (7:9) ​

Answer 1

Answer:

I tackle all of these types of problems by converting them to decimals, or giving them the same denominator. Let's try both ways.

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

Answer:

5:6

Step-by-step explanation:

5:6 can also be represented as 5/6

The same way 7:9 equal to 7/9

Now comparing them we take LCM which is 18.

So (5×3)/(6×3) and (7×2) / (6×3)

= 15/18 and 14/18

Hence 15/18 is greater.

Therefore, 5:6 is greater.
