The ratio of suitcases to screened suitcases is 36:8. The second ratio is 180:?.
--
180 is 5 times 36 which can be proven by dividing 180 by 36.
180 ÷ 36 = 5
Multiply 5 by 8 to find the amount of suitcases that would be screened if there were 180 total suitcases.
5 × 8 = 40
The first ratio is 36:8, and with a scale factor of 5 we get the second equivalent ratio 180:40.
Forty suitcases will be screened.
I hope this helps :)
