Answer:
40%
Step-by-step explanation:
In order to turn a fraction into a decimal or percentage, you need to make the denominator 100. In this case you just need to multiply the numerator and denominator by 20:
2/5 --> 2*20/5*20 --> 40/100
So, it is 40%. Though if you want to turn ANY fraction (specifically fractions with hard to multiply denominators) into a percentage, just follow this rule:
(100n/d)%
