Ty for checking my answers.

To check if the answers are correct, let's perform the calculations ourselves:

12) 2 1/7 x 3 2/3 = (15/7) x (11/3)
To multiply fractions, you multiply the numerators and the denominators separately.
Multiply the numerators: 15 x 11 = 165
Multiply the denominators: 7 x 3 = 21
So, the result is 165/21.
This fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 3 in this case.
Dividing 165 and 21 by 3, we get a simplified fraction: 55/7.
As a mixed number, 55/7 can be expressed as 7 6/7.

Therefore, your answer for question 12 is correct: 2 1/7 x 3 2/3 = 7 6/7.

13) 3/7 divided by 2/3 = (3/7) ÷ (2/3)
To divide fractions, you multiply the first fraction by the reciprocal of the second fraction.
The reciprocal of 2/3 is 3/2.
Multiply the fractions: (3/7) x (3/2)
Multiply the numerators: 3 x 3 = 9
Multiply the denominators: 7 x 2 = 14
So, the result is 9/14.
This fraction is already in simplest form.

Therefore, your answer for question 13 is correct: 3/7 divided by 2/3 = 9/14.

14) 1/8 divided by 3/4 = (1/8) ÷ (3/4)
Again, to divide fractions, you multiply the first fraction by the reciprocal of the second fraction.
The reciprocal of 3/4 is 4/3.
Multiply the fractions: (1/8) x (4/3)
Multiply the numerators: 1 x 4 = 4
Multiply the denominators: 8 x 3 = 24
So, the result is 4/24.
This fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 4 in this case.
Dividing 4 and 24 by 4, we get a simplified fraction: 1/6.

Therefore, your answer for question 14 is correct: 1/8 divided by 3/4 = 1/6.

15) 2 1/7 divided by 3 2/3 = (15/7) ÷ (11/3)
To divide fractions, you multiply the first fraction by the reciprocal of the second fraction.
The reciprocal of 11/3 is 3/11.
Multiply the fractions: (15/7) x (3/11)
Multiply the numerators: 15 x 3 = 45
Multiply the denominators: 7 x 11 = 77
So, the result is 45/77.
This fraction is already in simplest form.

Therefore, your answer for question 15 is correct: 2 1/7 divided by 3 2/3 = 45/77.

Great job! All of your answers are correct.
