Mia spent 30 minutes answering the math questions on the exam. This was 3/5 of the total amount of time allotted for this section of the exam. To determine the total amount of time allotted for this section of the exam, Mia set up and solved the equation as shown below.

3/5x = 30
5/3(3/5)x = 30(3/5)
X=18

Which best describes the error that Mia made?

A. Mia did not use the correct equation to model the given information
B. Mia should have multiplied both sides of the equation by 5/3
C. The product of 30(3/5) is not equal to 18
D. The product of 5/3 and 1/30 should have been the value of x

-6 is the correct option from the above given options

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.
