1. The entire course is 160 meters :) 2. Her essay is 18 pages long.
Step-by-step explanation:
1. The first step is to divide 60 by 3. That makes 20. So 20 is 1/8 of the entire course. Then you multiply 20 by 8 and you have 160. That makes the whole course 160 meters long.
You use the same steps for 1. to solve this one too!
2. The first step is to divide 15 by 5. That makes 3. So, 3 is 1/6 of the essay. Then you multiply it by 6. That makes 18. There are 18 pages in the essay. Hope this helped.
Since the 3 and 7 have 21 as a common multiple you can divide 21 by the denominator of each term and then multiply it by the numerator which get you while numbers
