1/6

Step-by-step explanation:

We are told that:

Ernesto used 2/3 of a cup of frosting to decorate some cupcakes.

He divided all the frosting equally among 4 cupcakes.

The amount of frosting Ernesto used on each cupcake is calculated as:

2/3 cup ÷ 4 cupcakes

= 2/3 × 1/4

= 2/12

= 1/6 of 2/3cup of frosting was used on each cupcake

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
