QUESTION 1
0.80
to make it a percentage you multiply it by 100
0.80 * 100 = 80%
and as a fraction it would be
80/100 = 4/5 in its simplest form
QUESTION 2
3/9
to change to percentage multiply it by 100
3/9 * 100 = 33 1/3%
as a decimal you divide the percentage by 100
33 1/3 divided by 100
= 0.3333333... = 0.33 (2dp)
QUESTION 3
6/8
percantage = 6/8 * 100 = 75%
decimal = 75% divided by 100 = 0.75
QUESTION 4
decimal = 66 2/3% divided by 100 = 0.666666... = 0.66 (2dp)
fraction = 66 2/3 over 100 = 2/3 simplified form

0.80 means that there are two digits after the decimal so write it like on numerator (above line) and add 100 under it (with 2 zeroes)
to become 0.80 = 80 / 100 as a fraction
Multiply the fraction with 100 to get percentage
so 80 / 100 X 100 = 80%
2) 3 / 9 = 1 / 3 (taking 3 common from 3 and 9)
multiply by 100 to get percentage
1 / 3 X 100 = 0.33 %
3) 6 / 8 = 3 / 4 (taking 2 common from 6 and 8)
% = 3 / 4 x 100
= 75 %
4) 66 2 /3 % is a mixed fraction percentage, so first solve it
to get 200 / 3 %
as it is already a percentage, you need to divide it by 100
so 200 / 3 x 1 / 100 = 2 / 3 (as fraction)
and as decimal it is 0.666

well, for future reference just remember that to find the decimal from a fraction divide the numerator by the denominator. multiply this by 100 to get the percent.
.80=80/100=80%
3/9=1/3=.33333...=33 and 1/3%
6/8=3/4=.75=75%
66 and 2/3%=2/3=.66666666...

Honestly, I don't remember how to explain this. But I can do it.
.8 = 4/5 = 80 %
3/9 = .333333333 = 33 1/3 %
6/8 = .75 = 75 %
66.66666 % = 2/3 = .6666666666
