The answer to your question is 5/4 or 1 1/4

Step-by-step explanation:

Data

distance traveled from home to the lake = 1 9/12

total distance = 4 9/12

distance traveled around the lake = ?

Process

1. - Convert the mixed fractions to improper fractions

a) 1 9/12 = (12 + 9) / 12 = 21/12 = 7/4

b) 4 9/12 = (48 + 9) / 12 = 57/12 = 19/4

2. - Multiply the distance from home to the lake by two

7/4 x 2 = 14/4 = 7/2

3. - Subtract the result of "2" from the total distance

19/4 - 7/2 = 19/4 - 14/4 = 5/4

5. - The distance around the lake is 5/4 or 1 1/4
