You walk 2/5 miles to a clothing store. Then you walk another 1/2 miles to a music store. How many miles have you walked in all?

9/10ths of a mile. Or 0.9 miles.

Step-by-step explanation:

To get the total it's helpful to look at it in decimals:

2/5 mile = 0.4 miles (1 mile divided by 5 = 0.2 miles, times that by 2)

1/2 mile = 0.5 miles

Add them together = 0.9 miles.

Which is 9/10ths of a mile.

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
