I have trouble solving word problems. Can you help me solve this problem?
If Sally can paint a house in 4 hours, and John can paint the same house in 6 hours, how long will it take both of them to paint the house together?

How did you get 10/24 then 24/10?

Remember: when dividing fractions, it is the same as multiplying by the inverse.
s/(b/c)= ca/b
so
1/(10/24)= 24/10

How did you get 10/24? Are you adding the fractions by useing the lease common denominator?
