To solve the problem, follow these steps:
Let's work through these steps:
Step 1: Find the Least Common Denominator (LCD) of the fractions involved. The denominators are 6, 4, and 12. The LCM of these numbers is 12, so the LCD is 12.
Convert each fraction to this common denominator:
Step 2: Perform the operations using these equivalent fractions:
Step 3: Check if the result can be simplified further. In this case, is already in simplest form.
Therefore, the solution to the problem is .
Complete the following exercise:
\( \frac{3}{4}:\frac{5}{6}=\text{?} \)
List the multiples of each number: 6 (6, 12, 18...), 4 (4, 8, 12, 16...), 12 (12, 24...). The smallest number that appears in all lists is 12, so that's your LCD!
To convert to denominator 12, ask: "What times 6 equals 12?" The answer is 2. So multiply both numerator and denominator by 2:
Yes, you can! and , but you'll still need a common denominator. Either method works - choose what feels easier!
Check if 11 and 12 share any common factors. Since 11 is prime and doesn't divide 12, 11 and 12 have no common factors except 1. So is already in simplest form!
Double-check your work! The LCD must be divisible by all original denominators: 12 ÷ 6 = 2 ✓, 12 ÷ 4 = 3 ✓, 12 ÷ 12 = 1 ✓. If your number doesn't divide evenly, it's not the correct LCD.
