What is 40% expressed as a fraction in simplest terms?

To convert a percentage into a fraction, you start by writing the percentage as a fraction over 100. For 40%, this means you write it as 40/100.

Next, you simplify the fraction. Both the numerator (40) and the denominator (100) can be divided by their greatest common divisor, which is 20 in this case. When you divide both by 20, you get:

40 ÷ 20 = 2
100 ÷ 20 = 5

This gives you the fraction 2/5.

Expressing 40% as 2/5 in simplest terms accurately represents the relationship between the percentage and its fractional equivalent, which makes this option correct.
