: 31. Write the decimal equivalent, using the bar notation. 2/9
10. Subtract. 6 3/10 - 4 11/15
18. Find the area of the shaded part in the figure. Use 3.14 for PIE and round your answer to one decimal place. It is a circle inside of a square with each side being 15ft.
21. Complete the statement, using the symbol < or >.

31. Write the decimal equivalent, using the bar notation. 2/9
= 0.2 with a bar over the 2
------------------------------------
10. Subtract.
6 3/10 - 4 11/15
= 63/10 - 71/15
= (3*63/30) - (2*71/30)
= (189 - 142)/30
= 47/30
-----------------
18. Find the area of the shaded part in the figure. Use 3.14 for PIE and round your answer to one decimal place. It is a circle inside of a square with each side being 15ft.
I don't know which part is shaded.
The area of the square is 15^2 = 225 sq ft
The area of the circle is (3.14)(7.5)^2 = 176.625
---------------------------------------
21. Complete the statement, using the symbol < or >.
15/17 __ 0.815
17/17 R 815/1000
Cross multiply to get:
17000 R 815*17
17000 R 13855
-------------------
Since 17000 > 13855
Therefore (15/17) > 0.815
