Question

How do you simplify and translate an expression “The sum of fifteen and a number plus twelve”?

Answer 1

Hint:If you need to answer these types of questions, then you need to be clear with the language. Unless and until you understand the question clearly, you cannot answer. Consider the number as a variable and let the number be x. Then, write the equation with the help of the language and hints, which is given in the question.

Complete step by step solution:
If you find these types of questions, you must know to pick up the numbers which are given in the question. The numbers which are given in the question are fifteen$\left( {15} \right)$, variable (let's suppose it to be x) and twelve $\left( {12} \right)$.
Now, we have to use the hint given in the language of the question to arrange all these numbers in an equation. We have to divide the sentence into two comparatively smaller phrases. The small phrases are “number plus twelve” and “Sum of fifteen and number”.
Interpreting the data and rewriting it in form of mathematical equation, we get,
$\left( {15 + x + 12} \right)$
On further simplification, we get,
$ \Rightarrow \left( {x + 27} \right)$

Note: The above-mentioned method can be remembered as a complete process for solving these types of questions. Be careful with the language while attending these types of questions, because there are many questions which may confuse you with the tricky and typical language. These types of questions are easy to solve when you are writing an exam as it takes less time to solve when you are thorough with this concept and have practised ample amounts of questions.
