Question

2.5% of a number is 100. What is a number?

Answer 1

Answer:

The number is 4000

Step-by-step explanation:

2.5% of a number. This means:

$0.025*x$

We know that this expression must be equal to 100 then:

$0.025x=100$

Now we solve the equation for the variable x

$0.025x=100$

Divide both sides of the equation by 0.025

$\frac{0.025}{0.025}x=\frac{100}{0.025}$

$x=\frac{100}{0.025}$

$x=4000$
