To find the number of surveyed participants of Spanish Club, we will first rewrite the given extended ratio. To do this, we will add x to each number.
2:3:7 ⇒ 2 x:3 x:7 xNow, we will use the fact that the total number of surveyed students is 36. This means that the sum of above terms needs to be equal to 36.
As we know the value of x, we can find the exact number of students that participate in each club.
2 x:3 x:7 x
2( 3):3( 3):7( 3)
6: 9:21
