Solve the following exercise:
To solve the expression , we will follow these steps:
Let's work through the steps:
Step 1: The denominators are 7, 2, and 14. The least common multiple (LCM) of these numbers is 14.
Step 2: Convert each fraction:
Step 3: Perform the operations:
Step 4: Simplify the fraction if possible. Here, simplifies to ; however, since the given choices list and it matches, there is no need for further simplification within the context of this question.
Therefore, the solution to the problem is .
Complete the following exercise:
\( \frac{3}{4}:\frac{5}{6}=\text{?} \)
Fractions represent parts of a whole, so you can only combine them when they represent parts of the same size. That's why you need a common denominator first!
List the multiples: 7: 7, 14, 21... 2: 2, 4, 6, 8, 10, 12, 14... 14: 14, 28... The smallest number that appears in all lists is 14.
It depends on the question! Here, simplifies to , but since the answer choices show , that's what they're looking for.
Lucky you! Like in this problem - it already has denominator 14, so you can leave it as is and just convert the others.
With addition and subtraction of fractions, you can work left to right once they all have the same denominator. Just be careful with your positive and negative signs!
