well, since both are divisible by 5; we can get the same results if we divide and get

what % of 6 is 3?

Answer 3

50%

Answer 4

good

Answer 5

Always remember that : we can write x% as : \(\large{\frac{x}{100}}\)

hence \[\large{\frac{x}{100}*30=15}\]
\[\large{\frac{x}{\cancel{100}^{50}}*\cancel{30}^{15}=15}\]
\[\large{\frac{x}{\cancel{50}^{10}}*\cancel{15}^3=15}\]
\[\large{\frac{x}{10}*3=15}\]
