Answer:
Step-by-step explanation:
You really don't even have to calculate anything.
B can be reduced to 4/5 by dividing 24 by 6 and 30 by 6
C can be reduced to 1/15 by dividing 2 by 2 and 30 by 2
D can be reduced to 1/2.
The answer then is A
2 feet is 2 * 12 = 24 inches.
24/30 = 4/5. See B.
(-2) +(-20) =-22
2+20=22 make result negative
-1/2 left and down 4
So it's #2
10 cm would stay as a 10 cm
14cm would round down to a 10
