Simplify 3/8+3/5 btw these are fractions thats why i put a /

First, find common denominators. Remember that what you multiply to the denominator, you multiply to the numerator too:

(3/8)(5/5) = 15/40

(3/5)(8/8) = 24/40

Simplify

15/40 + 24/40 = 39/40

39/40 is your answer

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
