On working on the work for the first problem so u understand
3/4 *10 is 7.5. 0.75 * 10 = 7.5
Answer:
150 people
Step-by-step explanation:
20/50 = 40%
So 40% are wearing hats and 60% aren't
0.6=60%
250x0.6= 150
There are 66.666666 etc..... so if you round you get
67%
the difference from 240 to 120 is 50%
