20

Each of the numbers 8, 18, ... 98 has an 8 in the units digit. That's 10 8's.

Each of the numbers 80, 81, ... 89 has an 8 in the tens digit. That's 10 more 8's.

(You could do this yourself just by writing down all the numbers.)

2 and five eights in percentage = 262.5%= 25/8* 100%=2 + 0.625* 100%= 2.625 * 100%= 262.5%

35/8

8 of them.

8-(8/8) = 7 This is an example of a mathematical diversion where all numbers between 1 and 100 are to be constructed from three eights (or any other number) 1=(8/8)8 2= (8+8)/8 and so on

(8/.8)*(8/.8)=100 all you really have to do is find a way to use two eights to make the number ten.

Between 1 to 100 there will be: 8,18,28,38,48,58,68,78,80,81,82,83,84,85,86,87,88,89 & 98: total 20 eights. This will be true for all the other sets of 100 barring 800 to 899 which will have an additional 100 eights. So the answer will be 20 * 10 + 100 = 300.

In 1 there are 8 eights. So 40 * 8 = 320. So there 320 eights in 40.

5/8 x 100= 62.5% 5/8 x 100= 62.5%

6/8 = 75/100 = 75%
