PLEASE HELP! ASAP! Karina is baking bread. She buys a small bag of flour that contains 2 2/3 cups of flour. The recipe calls for 2 5/7 cups of flour. Does she have enough flour to bake the bread? Explain how she can compare the fractions to know for sure.

She does NOT enough flour. (see below for explanation)

Step-by-step explanation:

We are given two mixed fractions. One way of comparing the two fractions is to convert them both to improper fractions and then making the denominator the same

Step1: Expressing both fractions as improper fractions:

2 2/3 = 8/3

2 5/7 = 19/7

Step 2: Convert fractions so that they have the same denominator.

We can simply do this by multiplying the numerator and denominator of each fraction by the denominator of the other fraction

for example for 11/3, the denominator of the other number is 7, hence we multiply both numerator and denominator by 7:

We do the same for 19/7

comparing 56/21 and 57/21, it is clear that if she needs 57/21 (which corresponds to 2 5/7) cups of flour, then if she has a bag that contains 56/21 (which corresponds to 2 2/3) cups of flour, that she will NOT have enough flour.

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%
