Richard is working 30 hours a week. For the first three days 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. h +21 1/5:= h= hours

The equation that represents the number of hours Richard needs to work to reach 30 hours for the week is h + 21 1/5 = 30.

To solve the equation, we need to isolate h on one side of the equation.

First, we can subtract 21 1/5 from both sides of the equation:

h + 21 1/5 - 21 1/5 = 30 - 21 1/5

Simplifying both sides:

h = 8 4/5

So Richard needs to work 8 4/5 hours to reach 30 hours for the week.
