Find the length whose 18 per cent is 27 cm.

1.	Find the length whose 18 per cent is 27 cm.
Answer» Answer: Let's call the PERCENTAGE we are looking for "p%". "PERCENT" or "%" means "out of 100" or "per 100", Therefore p% can be WRITTEN as p 100 . When DEALING with percents the word "of" means "times" or "to multiply". Putting this altogether we can write this equation and solve for n while keeping the equation balanced: Y = Z * 100÷x X = 18% & Z = 27 27 x 100÷8 = ? = 27 x 100÷18 = 150 Y = 150

Answer:

Let's call the PERCENTAGE we are looking for "p%".

"PERCENT" or "%" means "out of 100" or "per 100", Therefore p% can be WRITTEN as

100

When DEALING with percents the word "of" means "times" or "to multiply".

Putting this altogether we can write this equation and solve for

while keeping the equation balanced:

Y = Z * 100÷x

X = 18% & Z = 27

27 x 100÷8

= ?

= 27 x 100÷18

= 150

Y = 150
