Question

explain how to determine whether or not 11/12 is the correct answer to the problem 1 1/4 - 1 / 3

Answer 1

Answer:

11/12 is correct

Explanation:

To find the result of 1 1/4 - 1/3, we need to write the first number as a fraction, so:

$1\frac{1}{4}=\frac{(1\times4)+1}{4}=\frac{4+1}{4}=\frac{5}{4}$

Then, 1 1/4 - 1/3 is equivalent to 5/4 - 1/3, so the correct answer is:

$\frac{5}{4}-\frac{1}{3}=\frac{5(3)-4(1)}{4(3)}=\frac{15-4}{12}=\frac{11}{12}$

Therefore, 11/12 is the correct answer to the problem
