Answer:

$2\pi \approx 6.28\ meters$

Step-by-step explanation:

Mei's horse is 3 meters from the center of the carousel. After one rotation, Mei travelled

$l_M=2\pi r=2\pi \cdot 3=6\pi\ meters$

Anju's horse is 2 meters from the center. After one rotation, Mei travelled

$l_A=2\pi r=2\pi \cdot 2=4\pi\ meters$

The difference in their travelled distances is

$l_M-l_A=6\pi -4\pi =2\pi \approx 6.28\ meters$

First of all, you have to find the common difference between the numbers. That will be;
3/4-3/8=1 1/2-1 1/8
In the case of 1 1/2-1 1/8, the two whole numbers will subtract each other(1-1)
That will leave you with 1/2-1/8
3/4-3/8=1/2-1/8
The common denominator in both cases is 8
In 3/4-3/8
Divide 8 by 4 and multiply by 3 which will be 6
Divide 8 by 8 and multiply by 3. That will be 3
So you have; 6-3/8
Which is 3/8
If you do the same to 1/2-1/8, you will still end up with 3/8
Next, to find the fraction required to make 6 batches, you need to add 3/8 to the last term to the last term
1 1/2+3/8
3/2+3/8=12+3/8
15/8. This is the fifth batch. Add 3/8 again to get the sixth batch
15/8+3/8=15+3/8
18/8
Which is 9/4 when divided. The sixth batch is 9/4 or 2 1/4 in mixed fraction
Hope that helped. Have a nice day
