I am taking the test right now

Answer 2

3/8 mile in 3/5 hour

`( (3)/(8) )/( (3)/(5) )`
we want to find miles per hour or m/1h
convert 3/5 to 1 by multiplying it by 5/3
keep the fraction the same by multiply ing the whole thing by

`( (5)/(3) )/( (5)/(3) )` to get


`( (15)/(24) )/( (15)/(15) )`=

`( (5)/(8) )/( 1)`=5/8 miles per hour
