Question

Increase 48m by 20%? Help Please I'm Useless At Math<3

Answer 1

We have 48 meters.
We need to increase it by 20%.
That means we have 48 and then we increase it by 20%.

That can be expressed as:
48 + (48 * 20%)

Now, another way to write that would be:

48 * 120%

Now, 120% is nothing but 120/100. This can even be simplified to 1.2.

48 * 120%
= 48 * 1.2
= 57.6

48m increased by 20% is 57.6m.

Answer 2

You multiply 48m with 20% and add that to 48m.
20% can be written as 20/100.

$48m\times\frac{20}{100}+48m$

$\frac{48m\times20}{100}+48m$

$\frac{960m}{100}+48m$

$9.6m+48m$

${\boxed{57.6m}$
