A number when multiplied by 3 gives 6666 as answer The same number when multiplied by 6 gives A) 6666x2 B) 6666x3
C) 6666x6
D) 6666x18

A) 6666x2

Step-by-step explanation:

6,666 ÷ 3 = 2,222

2,222 × 6 = 13,332

6,666 is 3x more than 2222

so divide 6 by 3 to make it equal

(2,222 × 3) × (6 ÷ 3) = 13,222

6,666 × 2 = 13,332

it is a reproduction.

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
