1st one 17/100 2nd one 0.25
Because 0.17 would be like 17% out of 100% so the fraction simplified is 17/100
2. Since the area of a square is length×length
But according to the question we are asked to find the length and the area is given so we will have to solve this
L×L= area
L^2=0.25
Square root both sides
L=√0.25
L=0.5
Therefore the length of the square is 0.5
x = 1/120
i did not see the comment about the 1/5 until now
hope this helps
