3. A machine can produce 120 parts in 8 minutes. At this rate, how many parts can the machinist produce in 15 minutes? can you plz help me???? step by step the one who tells me it is good will get the crown

Answer 1

Ratio remains same

Let that be x

`\\ \rm\Rrightarrow 120:8=x:15`

`\\ \rm\Rrightarrow 15=x:15`

`\\ \rm\Rrightarrow x=15^2`

`\\ \rm\Rrightarrow x=225parts`

Answer 2

Let’s see how many parts per min
120 parts/8 minutes = 15 parts per minute
15 parts * 15 minutes = 225 in 15 min.
Solution: 225 parts
