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 + 21 1/5 = 30
h = [] hours

Answer 1

h + 21 1/5 = 30

To solve this equation, we need to isolate h by subtracting 21 1/5 on both sides:

h = 30 - 21 1/5

To subtract 21 1/5 from 30, we first need to convert 30 to a fraction with a denominator of 5:

30 = 30 * 5/5 = 150/5

Then, we can subtract 21 1/5 from 150/5:

150/5 - 21 1/5 = (150 - 105 - 1) / 5 = 44/5

Therefore, h = 44/5 hours.
