63/80 x 100 = 78.8%
You divide normally but multiply by 100 (moving the decimal over two places).
If this is correct the answer would be
y^2 + 0.1y + 0.0025
The answer is the last one; to express very large or small numbers.
We use it so we can show big or very small numbers in an easier way.
Let the numbers be x and y.
x*y=HCF*LCM=6*60=360
thus
y=360/x
next we find the list of combinations of x and y and test if they satisfy the conditions above:
(6,60),(12,30),(18,20),(24,15)
out of the above, only (6,60) and (12,30) satisfy both conditions. Thus our answer is:
(6,60) or (12,30)
