Answer 2

To find the decimal u divide 1 by 4 so you get 0.25. to get percent you multiply by 100 to get 25%
for the 2nd one you have the percent of 45% and to find decimal you divide by 100 to get 0.45 fraction --> 0.45 = 45 / 100 = 9 / 20
3rd one fraction is 3/10 which is 0.3 and 30%
4th you have decimal 0.4, multiply by 100 to get 40% and 0.4 = 4 / 10 = 2/5
5th one 80% -> 0.8 --> 8/10 = 4/5
last one 0.5 = 1/2 = 50%
