The **value **of the unknown **number **is 40.
What is the value of the unknown number?
Given the parameter :
"140% of what number is 56"
Let's represent the unknown number as "x."
To find the **number **that represents 140% of a certain value, simply set up an equation .
140% of the number = 56
140% of x = 56
140% × x = 56
First, convert the percent to decimal:
140% = 140/100 = 1.4
Now, we have:
1.4 × x = 56
Solve for x.
Divide both sides of the equation by 1.4:
x = 56/1.4
x = 40
Therefore, the **value **of x is 40.
