Answer 2

To simplify the expression 8/9 : 7/10 : 8/3 and then multiply it by 89/167/12, you can follow these steps:

1. Simplify the ratio 8/9 : 7/10 : 8/3: To make the denominators the same, find a common denominator for 9, 10, and 3, which is 90. Then, rewrite each fraction with a denominator of 90:

   (8/9) = (8/9) * (10/10) = 80/90 (7/10) = (7/10) * (9/9) = 63/90 (8/3) = (8/3) * (30/30) = 240/90

   So, the simplified ratio is 80/90 : 63/90 : 240/90.

2. Now, multiply the ratio by 89/167/12:

   (80/90) * (89/167/12) = (80/90) * (72/112) = (8/9) * (8/14) = 64/126

So, the final result is 64/126. You can also simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 2:

(64/2) / (126/2) = 32/63

So, 89/167/12 is equal to 32/63.
