Answer:
18 3/4
Explanation:
First, we need to convert the mixed numbers into fractions, so:
It means that Shamika worked 25/2 hours last week and this week she worked 3/2 times the hours worked last week. So, to know the number of hours worked this week we need to multiply 25/2 by 3/2 to get:
Then, 75/4 as a mixed number is equal to:
Because when we divide 75 by 4, we get 18 as a quotient and 3 as a remainder.
Therefore, she worked 18 3/4 hours this week.
