Question

33% of a fairy cake is sugar. Write this number as a decimal

Answer 1

.33 because percents are always out of 100 and 33/100 is the same as .33

Answer 2

When converting a decimal to a percent, the decimal is moved two place values to the right, so when converting a percent to a decimal, move the decimal two place values to the left.  So 33% = 0.33
