Question

Find the missing number:

Answer 1

Answer:

20%

Step-by-step explanation:

Not sure if this is exactly correct, but let's say we start with 1 unit. If it increased by 25%, we get:

1 × 1.25 = 1.25 units.

Now, to get back to 1 unit, we need to find:

1.25 × ?  = 1

? = $\frac{1}{1.25}$ = 0.80

So, 100% - 80 % = 20%

A 20% decrease.

Not completely sure though.
