Answer:
His sister has 2 5/12 pounds of candy.
Explanation:
She has 1 3/4 + 2/3
= 7/4 + 2/3 The LCD of 4 and 3 is 12 so we have:
7*3 / 12 + 2*4 / 12
21/12 + 8/12
= 29/12
= 2 5/12 pounds of candy.
2 5/12
You have to add 1 3/4 and 2/3 together. You find the common denominator, 12, and convert the fractions. 1 3/4 becomes 1 9/12 and 2/3 becomes 8/12. 1 9/12 + 8/12 is 1 17/12. 1 17/12 simplified is 2 5/12.
