Solve the following expression:
According to the order of operations, we will first solve the expression in parentheses.
Note that since the denominators are not common, we will look for a number that is both divisible by 2 and 3. That is 6.
We will multiply one-third by 2 and one-half by 3, now we will get the expression:
Let's solve the numerator of the fraction:
We will combine the fractions into a multiplication expression:
Complete the following exercise:
\( \frac{1}{2}:\frac{3}{5}=\text{?} \)
The order of operations (PEMDAS) requires parentheses first! If you multiply by each fraction separately, you're actually solving , which is a completely different problem.
Find the Least Common Denominator (LCD)! For , the LCD is 6. Convert: and , then add to get .
Multiply straight across! For , multiply numerators: 1 × 5 = 5, then denominators: 4 × 6 = 24. Result: .
Work backwards! Start with and divide by : . This should equal your parentheses result!
Remember, you're multiplying by , which makes the result smaller! Since from the parentheses gets multiplied by a fraction less than 1, the final answer must be smaller than .
