Respuesta :

What percentage of 1.16 is 2.22?  The amount over 100% will be the increase:

2.22 = (x/100)(1.16)

x = 2.22(100)/1.16

x = 191.4%

The increase is 91.4%

Answer:

A.

Step-by-step explanation:

(I'm not sure if this is right so let me know)

If you divide 1.20 by 2.22 it comes out as 0.5405. If you take this and round, you get 0.541. After this, to make it a percentage, you move the decimal 2 places left, which comes out as 54.1%

Hope this helps!
