Answer 3

[AI-generated answer — Bot GPT 3.5]

To find the total number of books Kylie and Brady have read together, we need to add the number of books each of them has read.

Kylie read 5 ½ books, which can be written as a mixed number.
Brady read 6 ¼ books, which can also be written as a mixed number.

To add mixed numbers, we need to make sure they have the same denominator.

The denominator of ½ is 2, and the denominator of ¼ is 4.

To find a common denominator, we can multiply the denominators together: 2 * 4 = 8.

Now, we can convert the mixed numbers to have the same denominator of 8.

5 ½ can be written as 5*8/2*8 = 40/8.
Similarly, 6 ¼ can be written as 6*8/4*8 = 48/8.

Adding these fractions together, 40/8 + 48/8 = (40 + 48)/8 = 88/8.

Now we can simplify this fraction by finding the greatest common divisor (GCD) of 88 and 8, which is 8.

So, to find the total number of books Kylie and Brady have read together, we divide both the numerator and denominator by 8: 88/8 ÷ 8/8 = 11.

Therefore, Kylie and Brady have read 11 books together.

Answer 5

[AI-generated answer — Bot GPT 3.5]

To find the total number of books Kylie and Brady have read together, we need to add the number of books each of them has read.

Kylie read 5 ½ books and Brady read 6 ¼ books.

To add mixed numbers, we need to make sure they have the same denominator.

5 ½ can be written as 5/1 + 1/2 = 10/2 + 1/2 = 11/2.

6 ¼ can be written as 6/1 + 1/4 = 24/4 + 1/4 = 25/4.

Now we can add these fractions: 11/2 + 25/4.

To add these fractions, we need to find a common denominator. The least common multiple (LCM) of 2 and 4 is 4.

Converting the fractions:

11/2 * 2/2 = 22/4.

Now we can add the fractions: 22/4 + 25/4 = 47/4.

This fraction cannot be simplified further.

So the total number of books Kylie and Brady have read together is 47/4.

To convert this result back to a mixed number, we need to divide the numerator (47) by the denominator (4):

47 ÷ 4 = 11 remainder 3.

Therefore, the mixed number is 11 ¾.

Therefore, Kylie and Brady have read 11 ¾ books together.
