It is generally believed that an A4 piece of paper can be folded in half approximately seven to eight times due to the thickness of the paper increasing with each fold, making it increasingly difficult to fold further.
Standard copying paper is A4, fold it in half and you get a A5. Fold it in half again and you get a A6, one last fold and you got a A7. So a A7 paper is a paper with the same proportions as a A4 paper but with 1/8 of the area. A7 size is 74mm x 105mm
Just fold it in half. A4 is 210 x 297 mm; A5 is 148 x 210 mm.
9 10ths
7 10ths.
1 and 2/10ths or 12/10ths
No, it does not. Take a sheet of A4 paper and fold it across the diagonal, and you will see that the two halfs do not line up.
Since 0.8 is equal to 8/10ths, -0.8 is equal to -8/10ths and -0.80 is also equal to -8/10ths. If you simplify -8/10ths by dividing the numerator and the denominator by 2 you get :-4/5ths
Since its .29 the fraction for .20 is 2 10ths so it would have to be 9 10ths.

There are plenty of techniques to making a paper airplane! To get a simple, basic airplane, fold a piece of a4 in half to create a long, skinny piece. Then fold two adjacent corners inwards at right angles. Fold these right angles in towards the center line again to create 45 degree angles. Close the paper by its fold and fashion two wings out of the ends of the paper and Viola!
Yes. You can. If you fold it, turn 90 degrees and fold it again. I saw it on myth busters. They folded a paper the size of a football field 11 times. with the help from NASA. But with a regular 11x8 paper, i don't think it is possible.
