Solve the following exercise:
To solve this problem, we will follow these steps:
Now, let's work through each step:
Step 1: The least common multiple (LCM) of 10 and 6 is 30. So, our common denominator will be 30.
Step 2: Convert each fraction to have a denominator of 30:
For :
For :
Step 3: Add the fractions:
Step 4: Simplify if needed:
The fraction is already simplified to one of the given answer choices with a common denominator, matching one of the options.
Therefore, the solution to the problem is .
Complete the following exercise:
\( \frac{3}{4}:\frac{5}{6}=\text{?} \)
List the multiples of each number: 10: 10, 20, 30, 40... and 6: 6, 12, 18, 24, 30... The first number that appears in both lists is 30, so that's your LCD!
Because fractions represent parts of a whole. You can only add parts when they're the same size! means 5 tenths, while means 1 sixth - these are different sized pieces.
It depends on what the problem asks for. In this case, matches one of the answer choices, so we keep it as is. But generally, it's good practice to simplify to .
Don't worry! The process is exactly the same. You might need to use prime factorization to find the LCD more easily, but the steps remain: find LCD, convert fractions, add numerators.
Yes, but it makes the problem harder! You could use 60 instead of 30, but then you'd work with bigger numbers. The LCD keeps numbers smaller and calculations simpler.
