1 m = 100 cm 1 sq m = 1 m x 1 m = 100 cm x 100 cm = 10000 sq cm ⇒ 80000 cm2 = 80000 ÷ 10000 m2 = 8 m2

The circle is 100% or 100/100.You want 1/8 of 100. that's (1/8)*100=100/8=12,5%
100 percent over 8 = 1/8 or 0.125= 100%/8= 1/8 or 0.125
800
To find this divide 100 by 1/8 That is (100)/(1/8) = 800
percent of 1 out of 8 = 12.5% % rate:= 1/8 * 100%= 0.125 * 100%= 12.5%
1/8, as a percentage = 100*(1/8) = 100/8 = 12.5%
1/8 of 1% = 1/8 of 1/100 = 1/8*1/100 = 1/800
percentage = 800%% rate:= 8/1 * 100%= 8 * 100%= 800%
equivalent percentage for 1 out of 8 = 12.5%% rate:= 1/8 * 100%= 0.125 * 100%= 12.5%
100 cm = 1 m100 cm / 8 m = 1 m / 8m = 1/8 = 0.125
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.
6 1/8:= [6 + (1 ÷ 8)] x 100%= [6 + 0.125] x 100%= 6.125 x 100%= 612.5%
