I need some help ,please...with calculator function on Computer

[Magyar]

Here's my dilemma:

Hank has this plastic hand -held calculator that is working more efficiently than my computer calculator..but it could be that I am malfunctioning in my procedure.

The example is a Ratio example: $600 is what percent of $1500?....easy example....

I can calculate this very easily using simple algebra, but Hank's manual shows how this example is done on his calculator ( see photo, please)

I tried doing this with my computer calculator and it doesn't work unless I do an additional multiplication of the .4 answer by 100...then the screen shows 40.

My question: why would I have to do an additional step ..,, I would think that the computer calculator would do just as well as a plastic hand -held one.


The "calculation " example just above the ratio example worked perfectly on my computer calculator...so what's the problem with the ratio calculation?

Soooooo would someone pullllllllllllleeeeeeeeeeeeeeeeze try this example on their computer calculator and tell me if it's me ...or the calculator who needs help .Sheeeeeeeeesh! I've studied Algebra, Geometry and Calculus, and yet I don't know how to use a calculator?? Embarrassing!:blush:

I am very appreciative someone (s) to figure this out and post an answer to this situation

THANK YOU

Set it up this way 600 / (1500%) = .4 or 40

See if that does not work out for you. I did this on my TI-92% graphics calculator and I came up with 40 for an answer.
When I left off the % the answer ends up being .400. I have my calc set up to display 3 digits past the decimal.
