candice spent 34/5 hours and shane spent 2 1/10 at track practice over the weekend how many more hours did candace spend at the track than shane

Answer 1

3 4/5 = 3.8

2 1/10 = 2.1

3.8-2.1 = 1.7 hours more

OR maybe you meant 34/5 and 21/10?

if so then

34/5 =68/10

68/10 -21/10 =47/10 = 4.7 more

when subtracting fractions

either convert them to the same common denominator, then subtract the numerators

or convert them to decimal form
