Question

a florist has 45 tulips in his shop. 20% of the tulips are yellow. How many tulips are yellow?

Answer 1

Multiply 45 by 1/5, or 0.2, and you will get an answer of 9, which is the amount of tulips that were yellow. You will know that you need to multiply 45 by either 1/5 or 0.2 because you can make a fraction 20/100 and simplify it to 1/5, or you can move the decimal point in 20.% two times to the left getting the decimal to divide the amount of tulips by

Answer 2

10% = 45
20% = 90
90 tulips are yellow

hope this helps you
