HELP PLEASE

the answer is 7/6 cups

Step-by-step explanation:

You add 1/2 + 2/3 and then you make sure the denominators are the same. It will turn into 3/6 + 4/6 and when you add that you get 7/6 cups.

it is answer C: 7/6

Step-by-step explanation:

1/2 = 0.50 ( division )

2/3 = 0.66 ( division )

0.50 + 0.66 = 1.16 ( addition )

answer c is 7/6 7 divided by 6 is 1.16.

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.
