Harry rides his bike 25 3/8 miles. karen rides her bike 25 2/5 miles. who rode farther? ( explain! )

Karen

Step-by-step explanation:

Since neither 3/8 or 2/5 can be simplified further, you need to multiply them by the LCM to get the same denominator.

The LCM of 5 and 8 is 40.

Multiply 3/8 by 5 ( both numerator and denominator)(turns into 15/40 )

Multiply 2/5 by 8 ( both numerator and denominator)(turns into 16/40)

Now that they have the same denominator, we can see which one is closest to a whole mile.

16/40 is greater than 15/40, so Karen rode farther.

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

one that is bigger than 3 1/2
