Mariana jogged 1/2 of a mile to get from school to the park. Then she jogged 3/10 of of mile to get to the store. What is the total number of miles Mariana jogged

Okay, I think the easiest way to approach this problem is to first convert the mixed fractions to irregular fractions:

8

1

8

=

8

⋅

8

+

1

8

=

65

8

7

2

5

=

7

⋅

5

+

2

5

=

37

5

We want the total number of miles, so our equation is:

distance=

65

8

+

37

5

The LCD of 5 and 8 is 5*8=40, so:

distance=

325

40

+

296

40

distance=

621

40

=

15

21

40

miles.
