Question

Middle School Debate Club 30% members are in 6th grade. If there are 12 6th graders in The Debate Club, how many total members are there ?

Answer 1

We know that 30% of the members are in 6th grade, and add up to 12 members.

Lets X be the total members.

Then 0.3*X are in 6th grade, and this is equivalent to 12 members.

NOTE: 0.3 is the decimal form of 30%.

We can write:

`\begin{gathered} 0.3\cdot X=12 \\ X=(12)/(0.3) \\ X=40 \end{gathered}`

Answer: there are 40 members in the Debate Club.
