Put these in order from least to greatest
2.17x10^-2, 4.18x10^-4, 3.26x10^-3

Step-by-step explanation:

2.17 * 10-2 = 2.17 * 1/(10^2) = 2.17 / 100 = 0.0217

4.18 * 10^-4 = 4.18 * 1 / (10^4) = 4.18 / 10000 = 0.000418

3.26 x 10^-3 = 3.16 * 1 / (10^3) = 3.16 / 1000 = 0.00316

least to greatest is :

(1) 4.18 * 10^-4

(2) 3.26 * 10^-3

(3) 2.17 * 10^-2

Step-by-step explanation:

2.17x10^-2 = 0.0217

4.18x10^-4 = 0.000418

3.26x10^-3 = 0.00326

Ascending order: 0.000418 ,  0.00326  , 0.0217

4.18x10^-4 ;   3.26x10^-3 ;   2.17x10^-2

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

the correct answer is 5 6 and 7
