Liam and Kaiden are brothers who go to different schools. The school day is just as long at Liam's school as at Kaiden's school. At Liam's school, there are 6 class periods of the same length each day. Kaiden's day is broken into 3 class periods of equal length. One day, it snowed a lot so both of their schools started late. Liam only had four classes and Kaiden only had two. Kaiden claims his school day was shorter than Liam’s was because he had only two classes on that day. Is he right? PLEASE HELP!!

He's not right

step-by-step explanation:

you are throwing one dart

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.
