\(\left(\frac{r}{s}\right)(3)=\)
Answer (1)
Multiply the fraction s r by 3.
Multiply the numerator by 3: 3 .
Keep the same denominator s .
The simplified expression is s 3 r .
Explanation
Understanding the Expression We are given the expression ( s r ) ( 3 ) and asked to simplify it. This involves multiplying the fraction s r by the number 3.
Performing the Multiplication To multiply a fraction by a whole number, we multiply the numerator of the fraction by the whole number and keep the same denominator. In this case, we have:
Result of the Multiplication ( s r ) ( 3 ) = s 3 r
Final Answer Therefore, the simplified expression is s 3 r .
Examples
In real life, this type of calculation can be used when scaling recipes. For example, if a recipe calls for s r cups of flour and you want to triple the recipe, you would multiply s r by 3 to find the new amount of flour needed, which is s 3 r cups. This applies to any ingredient where you need to scale the quantity proportionally.
