Percentages

Question

Express 11 cents as a percentage of $3.40. Show full working

Thank you :)

Answer 1

First convert $3.40 to cents. $3.40 = 340 cents

 

So 11 cents out of 340 cents = X/100.   In other words 11/340 = X/100

 

so X = 11*100/340 = 1100/340 = 3.24%

 

So we can say that 11 cents = 3.24% of 340 cents
