Mikhail believes he can use the multiplication expression 1/2x6 to find the total number of

pound servings of rice he can make

from 6 pounds of rice. Which statement best explains why Mikhail is correct or incorrect?

Mikhail is correct in using a multiplication expression because the product of 6 and 1/2 is an integer.

Mikhail is correct in using a multiplication expression because 1/2 is the number of servings per pound.

Mikhail is incorrect in using a multiplication expression because the term "total" implies finding the sum of an addition

expression.

Mikhail is incorrect in using a multiplication expression because the question asks how many equal-sized parts 6 can be

divided into.

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.
