Question

You run 4 miles each week. On Monday, you run 1/2 mile. On Tuesday, you run 1/3 mile. How much farther do you run on Monday than on Tuesday?

Answer 1

You can ignore the "4 miles" in this problem!
You walk further (1/2 mile) on Monday than on Tuesday (1/3 mile). All you have to do is to subtract 1/3 mile from 1/2 mile. What is the LCD here? 6.

Can you now do the subtraction?

Answer 2

1/2-1/3=3/6-2/6=1/6

1/6 of a mile. Good luck!
