80% of what number is 40 ?
I think the answer is 50 because if you do 0.8 multiple by 50 you get 40
0.8x = 40
Right, again!
To find out what number 80% of is equal to 40, we can use a simple algebraic equation. Let's call the unknown number "x".
The equation can be written as:
80% of x = 40
To solve for x, we need to convert the percentage to a decimal.
80% is equivalent to 0.80 (since percent means "per hundred," 80% is 80/100 which simplifies to 0.80).
Now, we can rewrite the equation as:
0.80x = 40
To isolate x, we divide both sides of the equation by 0.80:
x = 40 / 0.80
Evaluating this expression, we find that x is equal to 50.
Therefore, 80% of 50 is equal to 40.
