It is a common problem especially for those who are studying mathematics. It is a mathematical question which involves fraction and basic algebra. If 2/5 of a number is 14, the number can be determined by using algebraic equations. In this article, we will discuss the steps on how to solve this mathematical problem.
Step 1: Identify the variables
The first step in solving this problem is to identify the variables. In this case, the unknown variable is “x”, which is the number that we are trying to find. The other variable is “14”, which is the given value in the problem.
Step 2: Create an equation
The second step is to create an equation that includes both variables. Since we know that 2/5 of a number is 14, we can represent it in an equation as: 2/5 x = 14. This equation states that 2/5 of the unknown number is equal to 14.
Step 3: Solve the equation
The third step is to solve the equation. To do that, we need to isolate the variable “x”. To do this, we can multiply both sides of the equation by the reciprocal of the denominator, which is 5/2. This will cancel out the fraction on the left side and leave only “x” on the right side. The equation now becomes: x = 28. Therefore, the number which is 2/5 of 14 is 28.
In conclusion, if 2/5 of a number is 14, the number is 28. To solve this problem, we have to identify the variables first, create an equation, and then solve the equation by isolating the variable. After that, we can calculate the answer by multiplying both sides of the equation with the reciprocal of the denominator.
