Me with this assignment, i will reward 100 points for an honest and fair answer.

Order from least to greatest
-9/2, - 3, 1/2, sqrt(6), 4.2

answer
D.-9/2, - 3, 1/2, sqrt(6), 4.2


sqrt(10) is irrational number and real numbers
answer is B.irrational number and real numbers


square root (81) = 9
square root (100) = 10

square root (93) is between 9 and 10

so answer
9< sqrt(93) < 10

402.10 ÷ 200 = 2.0105

2.0105 × 0.86 = 1.72903

1.72903 ÷ 0.86 × 200 = 402.10
