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 the represents the number of hours ,h, Richard needs to work to reach 30 hours for the week and solve the equation

Answer 1

To find the number of hours, h, Richard needs to work to reach 30 hours for the week, we can use the equation:

h + 21 1/5 = 30

First, let's convert 21 1/5 to a fraction. We can rewrite it as:

21 + 1/5 = 21 + 1/5 * 1 = 21 + 1/5 = 21 + 1/5 = 21 + 1/5 = 21 + 1/5 = 21 + 1/5 = 21 + 1/5 = 21.2

Now, we can substitute this value in the equation:

h + 21.2 = 30

To solve for h, we can subtract 21.2 from both sides of the equation:

h + 21.2 - 21.2 = 30 - 21.2

This simplifies to:

h = 8.8

Therefore, Richard needs to work for 8.8 hours to reach a total of 30 hours for the week.
