Determine the ratio of defective telephones
ratio = 9/30
ratio = 3/10
3 of 10 telephones are defective
Determine the number of defective telephones each day
def telephone = ratio of defective × total production
def telephone = 3/10 × 1000
def telephone = 300
There are 300 defective telephones each day
You just need to trace it without moving your pencil off the paper
