A glass of water is $\dfrac{3}{7}$ full and $\dfrac{4}{7}$ empty. It has 6 ounces of water in it. How many ounces of water can the glass hold?

idk

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.

you would need to also lose 1 point for each of the other outcomes for it to be fair.

2 over 5 and 4 over 15

don’t know last one sorry
