Question

Mai biked 6 3/4 miles today , and Noah biked 4 1/2 miles . How many times the length of Noah’s bike did was mai’s bike rid

Answer 1

`(2)/(3)`

Explanation:

Mai biked
`6(3)/(4)` miles today. Convert the number of miles Mai biked into improper fraction:

`6(3)/(4)=(6\cdot 4+3)/(4)=(24+3)/(4)=(27)/(4)\ miles`

Noah biked
`4(1)/(2)` miles. Convert the number of miles Noah biked into improper fraction:

`4(1)/(2)=(4\cdot 2+1)/(2)=(8+1)/(2)=(9)/(2)\ miles`

To find the number of times the length of Noah’s bike did was Mai’s bike did, divide the Noah's number of miles by Mai's number of miles:

`(9)/(2)/ (27)/(4)=(9)/(2)* (4)/(27)=(2)/(3)`
