f) 12/250= 6/125
g) 1/100
h) 12.1/100=121/1000
Step-by-step explanation:
when you put % sign after any number, that means you divide the number by 100 or multiply the number by 1/100
so
(a) 18% = 18*1/100=18/100 (i don't think you have to simplify it, cuz we didn't do it in our school, but if there's any different rule in your school then you will have to simplify it, so for that case, i'll simplify it)
18/100= 9/50
(b) 85%= 85 * 1/100= 85/100=17/50
(c) 125%= 125*1/100= 125/100= 25/20= 5/4
(d) 210% = 210*1/100 = 210/100 = 21/10
(e) 0.25%= 0.25*1/100= 0.25/100= 25/10000= 1/400
(f) 4.8%= 4.8*1/100= 4.8/100= 48/1000= 12/250= 6/125
(g) 1%= 1*1/100=1/100
(h) 12.1%= 12.1*1/100= 12.1/100=121/1000
