What is 2/5% of 820?<br><br> 1.8<br><br> 2.05<br><br> 2.88<br><br> 3.28
Margarita [4]

Answer:

D) 3.28

Step-by-step explanation:

820/x=100/2.5

(820/x)*x=(100/2.5)*x       - we multiply both sides of the equation by x

820=40*x       - we divide both sides of the equation by (40) to get x

820/40=x

20.5=x

x=20.5

now we have:

2.5% of 820=20.5
