Question

Anna said that the product of 7/8 · 1 1/2 = 7/2. How can you tell that her answer is wrong?

A) The denominator cannot be the same as one of the factors.
B) The answer cannot be an improper fraction.
C) The answer must be less than 7/8.
D) 7/8 of a number cannot be greater than the number.

Answer 1

To determine if Anna's answer is correct, we need to evaluate the product of 7/8 and 1 1/2. By converting the mixed number to an improper fraction and multiplying the fractions, we find that Anna's answer is incorrect.

Step-by-step explanation:

To determine if Anna's answer is correct, we need to evaluate the product of 7/8 and 1 1/2. First, we need to convert the mixed number 1 1/2 into an improper fraction. To do this, we multiply the whole number (1) by the denominator (2) and add it to the numerator (1). This gives us 3/2. Now, we can multiply 7/8 by 3/2. When we multiply the numerators (7 and 3), we get 21. And when we multiply the denominators (8 and 2), we get 16. Therefore, the correct answer is 21/16, not 7/2. This means Anna's answer is incorrect.
