Solve Division Problem: Positive 1 ÷ 0.25

Since we are dividing two positive numbers, the result must be a positive number:

$+:+=+$

First, let's convert the numbers into fractions:

$1=\frac{1}{1}$

$0.25=\frac{25}{100}$

This leaves us with the folowing:

$\frac{1}{1}:\frac{25}{100}=$

Let's now convert the division into a multiplication, remembering to switch the numerator and denominator:

$\frac{1}{1}\times\frac{100}{25}=$

Let's now combine everything into one single exercise:

$\frac{1\times100}{1\times25}=$

Finally, we can solve the multiplication in the numerator and denominator to get our answer:

$\frac{100}{25}=4$
