Amachine takes 4.8 hours to make 8 parts. at that rate, how many parts can the machine make in 24.8 hours?

The machine can make 48 parts in 24.8 hours because if you times 4.8 times 5 you will get 24 but you need 24.8 so you would have to go up one more number which will be 6. After that you will need to times 6 and 8 to get the numbers of parts which is 48 but you can also count up 2 because 1 hr the machine can make 2 parts.

Hmmm i had this before , give me a sec
