Question

Write an expression for 40% of 25

Answer 1

For this case we must find an expression to find 40% of 25. So, we make a rule of three:

25 -----------> 100%

x -------------> 40%

Where "x" represents the amount that determines 40% of 25.

$x = \frac {40 * 25} {100}\\x = 10$

40% of 25 is 10. And an expression to find it is:

$x = \frac {40 * 25} {100}$

Answer:

$x = \frac {40 * 25} {100}$

Answer 2

Answer:

$\frac {40} {100}$ * 25

Step-by-step explanation:

We are asked to find an expression for 40% of 25.

Per-cent, as the name suggests, means one part in every hundred. To find 40%, we will divide the number 40 by 100. While the word 'of', in the mathematical context, means to multiply.

So the expression for 40% of 25 will be:

$\frac {40} {100}$ * 25
