I took a test yesterday with this question and got it right the answer is 3
A marching band has 1.5 times as many trumpet players as clarinet players.
i.e for every x number of clarinet players , the number of trumpet players= 1.5 x
Now, for every 2 clarinet players players, the number of trumpet players is given by 1.5=3 i’m not sure if it’s the same question but not sure
