Just remember that
1meter=100 cm
81.66m=81.66*100=8166 cm
3y-20+x+13=3x+9
3y-20+x+13+2y=180
3y-7+x=3x+9
3y=2x+16
y=2/3x+16/3
5y+x=187
5(2/3x+16/3)+x=187
10/3x+80/3+x=187
13/3x=481/3
x=37
5: 90 can also be written as a fraction 5/90 then reduce the fraction
5/90 (5*1=5/5*18=90) so it reduces to 1/18
the ratio simplified is 1:18
