Answer:
Part A- no because Kya lives 5.3 miles away from Carol while Orrin lives 0.58 miles away from Carol. Orrin lives closer since the distance from their houses is half a mile whilst Kya has 5 whole miles.
Part B- (remember each whole number represents a power of 10)
Calculate the expanded notation of 5:
(5x10^0)
(5x1)
Now the .153:
(divided by 10)
(1/10^1)+(5/10²)+(3/10³)
(1/10)+(5/100)+(3/1000)
(5x1) . (1/10)+(5/100)+(3/1000)
hope this helps :)
