When dealing with multiplication involving fractions and whole numbers, it's essential to understand the concept of multiplying fractions by whole numbers. In this case, we're given the expression . Our goal is to calculate the product of this expression.
Breaking Down the Problem
To solve this problem, we need to recall the rule for multiplying fractions by whole numbers. When multiplying a fraction by a whole number, we can simply multiply the numerator of the fraction by the whole number and keep the denominator the same.
Applying the Rule
Let's apply this rule to our given expression. We have . To find the product, we'll multiply the numerator (3) by the whole number (66) and keep the denominator (11) the same.
Performing the Multiplication
Now, let's perform the multiplication:
Simplifying the Expression
To simplify the expression, we can multiply the numerator (3) by the whole number (66):
Reducing the Fraction
Now that we have the expression , we can simplify it further by dividing both the numerator and the denominator by their greatest common divisor (GCD). In this case, the GCD of 198 and 11 is 11.
Calculating the GCD
To find the GCD of 198 and 11, we can use the Euclidean algorithm or simply list the factors of each number:
Factors of 198: 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198 Factors of 11: 1, 11
Dividing the Numerator and Denominator
Now that we have the GCD, we can divide both the numerator and the denominator by 11:
Final Answer
Therefore, the product of is .
