Cars are made in a factory at a rate of 39 cars every 3 hours. at this rate, how many cars can be made in the factory in 7 hours?

In 7 hours = 39 cars

so, 1 hour = 39/3 = 13 cars

Now, in 7 hours, it would be: 13*7 = 91 cars

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
