The decimal form of 80% is . 80 meaning you have 80 parts of 100 so the fraction would be expressed as 80/100. Then this fraction can be further reduced, first I would devide both the numerator and denominator by ten so you are left with 8/10 which can be further reduced.
3/5 x 3/5
=9/25
You have to multiply the 2 numerators (top) and then the 2 denominators (bottom)
4y=x
3(4y)-y=7012y-y=70
11y=70
y=70/11
4(70/11)=x
280/11=x
