disa [49]

This question was not well written

You walk 2/3 miles to a shoe store. Then you walk another 1/8 miles to a music store. How many miles have you walked in all? Write your answer as a fraction in simplest form.

Answer:

19/24 miles

Step-by-step explanation:

Number of miles walked to the shoe store = 2/3 miles

Number of miles walked to the music store = 1/8 miles

Total many miles have you walked in all = Number of miles walked to the shoe store + Number of miles walked to the music store

= 2/3 miles + 1/8 miles

Find Lowest Common Multiple = 24

= 2 × 8 + 1 × 3/24

= 16 + 3/24

= 19/24 miles
