During weekdays, Richard is working as a part-time library assistant at a university. He needs to work for a total of 30 hours a week. For the first three days of the week, he worked 21 1/5 hours. Complete the working equation that represents the number of hours, h , Richard needs to work to reach 30 hours for the week and solve the equation.(1 point)

Question

h = hours

Answer 1

h = 30 - 21 1/5

To simplify this equation, we need to convert 21 1/5 to an improper fraction.

21 1/5 is equivalent to (21*5 + 1)/5 = 106/5

h = 30 - 106/5

To subtract fractions, we need to have a common denominator.

30 can be written as 30/1.

h = 30/1 - 106/5

We can convert 30/1 to 150/5 to have a common denominator.

h = 150/5 - 106/5

Now we can subtract the numerators.

h = (150 - 106)/5

h = 44/5

Therefore, Richard needs to work 44/5 hours to reach 30 hours for the week.
