Letícia is dividing 2 3/4 pounds of trail mix equally among each of her four friends. How much does each receive

11/16 pounds each

Step By Step Explanation:

Change the mixed fraction to improper fraction

2 3/4 = 11/4

Divide the answer by 4

11/4 ÷ 4 = 11/16

Each friend gets 11/16 pounds

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.
