Answer:
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
