Solve the following exercise:
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: The denominators are 4 and 6. The least common multiple of 4 and 6 is 12.
Step 2: Convert each fraction to have the denominator 12.
For , multiplying the numerator and denominator by 3 gives .
For , multiplying the numerator and denominator by 2 gives .
Step 3: Add the fractions: .
Step 4: Check if can be simplified. Since 7 and 12 have no common factors other than 1, it is already in its simplest form.
Therefore, the sum of is .
Complete the following exercise:
\( \frac{3}{4}:\frac{5}{6}=\text{?} \)
Because fractions represent parts of different wholes! means 1 part out of 4, while means 2 parts out of 6. You need to make the wholes the same size first.
List the multiples of each number: 4: 4, 8, 12, 16... and 6: 6, 12, 18... The smallest number that appears in both lists is 12, so that's your LCD!
That's okay! In this problem, is already a proper fraction. But if you get something like , you can convert it to a mixed number or leave it as an improper fraction.
Yes, always check! Look for common factors between the numerator and denominator. Since 7 and 12 share no common factors except 1, is already in simplest form.
Multiply the numerator and denominator by the same number. For , multiply both by 3 to get . For , multiply both by 2 to get .
