1/3 of a number is added to 5 the result is one and half times the original number find the number
I don't know
To find the number, let's break down the problem into steps:
Step 1: Let's assign a variable to represent the unknown number. Let's call it "x."
Step 2: Translate the problem into an equation using the given information. According to the problem, 1/3 of the number is added to 5, resulting in one and a half times the original number. We can write this as:
1/3x + 5 = 1.5x
Step 3: Solve the equation for "x."
To do this, let's eliminate the fractions by multiplying all terms in the equation by 3 to clear the denominator:
3 * (1/3x) + 3 * 5 = 3 * 1.5x
x + 15 = 4.5x
Next, subtract "x" from both sides of the equation to isolate the variable on one side:
x - x + 15 = 4.5x - x
15 = 3.5x
Finally, divide both sides of the equation by 3.5 to solve for "x":
15 / 3.5 = x
x ≈ 4.286
So, the number is approximately 4.286.
