whats the percent

Question

Lashonda needs to make a total of 40

 deliveries this week. So far she has completed 18

 of them. What percentage of her total deliveries has Lashonda completed?

Answer 1

18/40 = 9/20 = 45/100 = 45% of the deliveries have been completed

20/40 is 50%, so you know you need slightly less than 50%
