Question

lily ordered a set of green and brown pin.she received 35 pins, and 80% of them were green.How many green pins did lily receive?

Answer 1

In total there are 35 pins so that correspound to the 100%, so we can use a rule of 3 to solve it so:

`\begin{gathered} 35\to100 \\ x\to80 \end{gathered}`

So the equation is:

`x=(35\cdot80)/(100)=28`

So there are 28 green pins
