Therefore, the solution to the problem is .
Complete the following exercise:
\( \frac{3}{4}:\frac{5}{6}=\text{?} \)
List the multiples of each number: 4: 4, 8, 12, 16... and 6: 6, 12, 18, 24... The smallest number that appears in both lists is 12, so that's your LCD!
Because and represent different-sized pieces! You need same-sized pieces (same denominator) before you can add them together.
Double-check your work! The LCD should be the smallest number that both denominators divide into evenly. For 4 and 6, it's definitely 12, not 24 or higher.
Always check! In this case, cannot be simplified further because 11 and 12 share no common factors other than 1.
Yes, but it makes more work! You could use 24 instead of 12, but you'd get , which simplifies to the same answer but with extra steps.
