Question

a factory make 30 cars in week how many cars does it make in 21 days​

Answer 1

Answer:

90 cars

Step-by-step explanation:

I think this will help

30 cars are made in 1 week = 7 days

Cars made in 21 days = x

                                          According to the Question

30/7 = x/21  ( Cross multiplication )

7x = 30 * 21  

x = 30 * 21 / 7   ( 7 cancels 21 and the answer is 3 )

x = 30 * 3

x = 90

So , 90 cars are manufactured in 21 days
