There was a girl in my class who used my calculator to write a message to another girl and I want to know if I can see what she wrote. Thanks

Your question is slightly vague... i know how she typed the mesage she pressed the 2nd key then the alpha key which puts the calculator into alpha lock mode... and after that she typed the message, however to my knowlege ther is no way to see a calculator that you are not holding in your hand or connected to with the cord... another problem you will have is most of the time one types something into an 83 after they hit enter it gives an error mesage saying something along the lines of "too few arguemnts" or "invalid expression" or something of the like and it doesnt save to the ram so finding out what she typed will be hard to do unless she shows you after she types it...

### Solving ratio problems

There is a problem with the numbers you quote.

20 x 2/3 = 13.3 boys

You can't have 0.3 of a boy. So round that off to 13 boys. Girls are

20 - 13 = 7 in number. This is the nearest sensible answer.

### There are 40 pupils in a class .twenty five of them are boys.what is the ratio of boys to girls?

If there are 40 total students, and 25 are boys, then (40-25) of them are girls, or 15.
That means the ratio of boys to girls is 25 to 15, or 25/15
This can be simplified by dividing by 5, so the ratio is 5/3

Here is your problem pasted again ingluding some of my thoughts. These thoughts and the answers to your questions are in CAPITAL.
There are exactly twelve children in Ryan's class. Only four of the children are boys. THAT MEANS THERE ARE 8 GIRLS. The following questions refer to a time when all the children are present in the class. THAT MEANS THE TOTAL PERSONS IN THE CLASS ARE 12 SINCE THERE IS NO MENTION ABOUT TEACHER. There are no visitors in the class. There might be more than one correct anwer to a question.

1. Which of the lettered statements must be true?
2. Which of the lettered statements cannot be true?
3. Which of the lettered statements could be true or not true?

a. There are twice as many girls as boys in Ryan's class. IS TRUE
b. There are eight more girls than boys in Ryan's class. IS FALSE
c. There are four more girls than boys in Ryan's class. IS TRUE
d. If Ryan is sitting at a table with all the girls, there are exactly nine children at that table. IS TRUE
e. If only three of the boys are standing on their heads, one of the boys is not standing on his head. IS TRUE.

In case of a problem or clarification, don't hesitate to post me a reply.
