Show your work on how you know these questions are correct

A.   is Repeating

B. is Terminating

C. is Repeating

Step-by-step explanation:

We know is Repeating because when it is in decimal form there is a line above the 6 in 0.6

We know is Terminating because when it is in decimal form there is no line above any of the numbers in 0.6

We know is Repeating because when it is in decimal form there is a line above 54 in 0.54.

Hope this helps.

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.
