john's house is 12 miles way from school. he is 2/ of the way home. how many miles has he walked

To find out how many miles John has walked, we need to determine 2/3 of the total distance from school to home.

Given that John's house is 12 miles away from school, we can calculate the total distance as follows:

Total distance = 12 miles

To find 2/3 of the total distance:

2/3 × Total distance = 2/3 × 12 miles

Simplifying the expression:

2/3 × 12 miles = (2 × 12) / 3 miles

Multiplying first:

(2 × 12) = 24

Then, dividing:

24 / 3 = 8

Therefore, John has walked 8 miles.

To calculate how many miles John has walked, we need to find 2/3 of the total distance between his house and school, which is 12 miles.

To do this, we can use the following calculation:

Distance walked = (2/3) * Total distance

Distance walked = (2/3) * 12 miles

Now, let's perform the calculation:

Distance walked = (2/3) * 12 miles
Distance walked = (2/3) * 12 miles
Distance walked = 8 miles

Therefore, John has walked 8 miles.

2/ * 21 = ____
