Question

Min read 1/8 of his book before lunch and 1/4 of his book after lunch. He says he has read 2/12​of his book.

Which statement is most accurate?


2/12 is a reasonable answer for the fraction of his book Min has read.

2/12 is not a reasonable answer for the fraction of his book Min has read. The fraction should be closer to 1/2.

2/12 is not a reasonable answer for the fraction of his book Min has read. The fraction should be closer to 1.

Answer 1

Answer:

2/12 is not a reasonable answer for the fraction of his book Min has read. The fraction should be closer to 1/2.

Step-by-step explanation:

First, find common denominators. Note that what you do to the denominator, you must do to the numerator:

1/8

1/4 x (2/2) = 2/8

1/8 + 2/8 = 3/8

Find common denominators between the amount he read as well as the amount he thinks he read:

(3/8)(3/3) = 9/24

(2/12)(2/2) = 4/24

Min has read 9/24 of his book, while he states that he read 4/24 of his book.

2/12 is not a reasonable answer for the fraction of his book Min has read. The fraction should be closer to 1/2.

Note: 9 is only 3 parts away from 12 (12/24), while 9 is 5 parts away from 4 (4/24).
