Vaughn paints his porch floor and also the porch floors of 9 neighbors. Each floor is a rectangle that is 8.4 feet long and 6.9 feet wide.

Part A
Which equations represent the best estimate of the total area of all the porch floors that Vaughn paints?
8 × 6 = 48; 48 × 9 = 432 square feet
8 × 7 = 56; 56 × 10 = 560 square feet
10 × 7 = 70; 70 × 10 = 700 square feet
10 × 10 = 100; 100 × 9 = 900 square feet

	8 × 6 = 48; 48 × 9 = 432 square feet
 	8 × 7 = 56; 56 × 10 = 560 square feet
 	10 × 7 = 70; 70 × 10 = 700 square feet
 	10 × 10 = 100; 100 × 9 = 900 square feet

ramen · Answer

Well for the first part, there would be a total of 10 porches Vaughn paints because he paints 9 neighbors' porches plus his which = 10. Now for the rounding part, if we were asked to estimate, how would we round 8.4 and 6.9? Hint: decimals greater than or equal to 5 round up, and less than 5 round down.
