hi Mandy,

What happened to your old calculator ?

Scientific calculators all work in much the same way. Have you got a manual ? I cannot download one from Canon. Their website seems to need some updating.

I suggest we take this one step at a time. When you want to use the calc. to do something, post a question about it.

(1) 45% correct!

(2) 22% nearly

(3) 75% correct!

(4) 8% No. Think about how many correct answers in this test

(5) 25% correct!

Can you change 2 and 4 ?

The answer to

(2) is 44/200 = 0.22 46/200 = 23% so 45/200 = 225%

(4) is 56/70 = 80%

Am I right

(4) is 56/70 = 80% correct

(2) is 44/200 = 0.22 46/200 = 23% so 45/200 = 225%

.22 = 22% .23 = 23% so I'm looking for an answer between these two.

You couldn't get a percentage score on a test that was over 100%

After you sort this one out, shall we have a break until tomorrow? What time can you log on?
