Answer:
<u>The two statements that apply are A and B.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
White envelopes Hadley has = 3/6 of a box
Gray envelopes Hadley has = 1/3 of a box
When full, each box of envelopes has the same number of envelopes
Hadley said she has 4/9 of a box when she puts the white envelopes and gray envelopes together.
2. Which statements describe this situation? Select the two statements that apply.
Let's add 3/6 and 1/3
3/6 + 1/3 = 3/6 + 2/6 = 5/6
A. Hadley’s answer is incorrect, because 3/6 is equal to 1/2 , and 4/9 is less then 1/2 . This is correct.
B. Hadley's answer is incorrect, because 3/6 plus 1/3 equals 5/6. This is correct.
C. Hadley's answer is incorrect, because 3/6 plus 1/3 equals 2/6. This is wrong
D. Hadley's answer is correct, because 3 and 1 is 4, and 6 and 3 is 9. This is wrong.
