Question

Kyle and Trinity go for a walk every morning. Kyle walks 2 1/4 miles. Trinity walks 1 3/8 miles less than Kyle. What is the total distance they walk every morning.

Answer 1

`3(1)/(8)\ mi`

Explanation:

we know that

Kyle walks 2 1/4 miles

Trinity walks 1 3/8 miles less than Kyle

Convert mixed number to an improper fraction

`2(1)/(4)\ mi= 2+(1)/(4)=(2*4+1)/(4)=(9)/(4)\ mi`

`1(3)/(8)\ mi= 1+(3)/(8)=(1*8+3)/(8)=(11)/(8)\ mi`

To find out the total distance they walk each morning, add the distance Kyle walks plus the distance Trinitry walks.

The distance Kyle walks is 9/4 miles

Find out the the distance Trinitry walks

Subtract 11/8 miles from the distance Kyle walks

`(9)/(4)\ mi-(11)/(8)\ mi=(2*9-11)/(8)=(7)/(8)\ mi`

Adds the distances

`(9)/(4)\ mi+(7)/(8)\ mi=(2*9+7)/(8)=(25)/(8)\ mi`

Convert to mixed number

`(25)/(8)\ mi=(24)/(8)+(1)/(8)\ mi=3(1)/(8)\ mi`
