There are 100 squares total. We need to find the proportion of cables that were defective.

6 / 120 = 3 / 60 = 1 / 20 = 0.05

You should shade 5 squares to show the fraction of cables that were defective.

We can find the percentage of defective cables by multiplying the proportion above by 100, because percentages are always out of 100.

0.05 x 100 = 5%

Hope this helps!! :)

hi!

6/120 × 100 = 5 so 5 grids need to be shaded

do you know why we need to ×100? because there are 100 grids

since there are 5 shaded grids and 100 grids in total, the fraction would be 5/100. so the percentage is 5%.

give me a brainliest if you want!
