The student government snack shop sold 40 items this week. snack type number of items sold
fruit cup 10
veggie sticks 8
chips 20
water 2
For each snack type, what percentage of all snacks sold were of that type?

40%

32%

60%

80%

Step-by-step explanation:

that is it im not sure if its right but i used a calculator

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.

multiple all that
