The percent increase from 18 to 26 is about...?

Shalnov [3]

Answer:

≈44.44%

Step-by-step explanation:

≈44.44%

To solve this, we can use a simple proportion.

Assuming 18 = 100%...

$\frac{18}{100}=\frac{26}{x}$

Then, using cross multiplication...

$18x=100(26)$

$18x=2600$

Now divide 18 from both sides.

x ≈ 144.44

Now subtract 100 from ≈144.44, leaving us with

≈44.44%
