Answer
Marco does 22 sit-ups on Tuesday and 45 jumping jacks on Wednesday.
Solution
Marco's workout ratio is constant. On Monday he does 54 jumping jacks and 18 sit‑ups, which simplifies to a 3:1 ratio (54 ÷ 18 = 3). This means that for every 3 jumping jacks, he does 1 sit‑up.
• Tuesday: If Marco does 66 jumping jacks, then he must do 66 ÷ 3 = 22 sit‑ups.
• Wednesday: If Marco starts with 15 sit‑ups, then he finishes his workout with 15 × 3 = 45 jumping jacks.
So, the values you should select are:
• Tuesday: 22 sit‑ups
• Wednesday: 45 jumping jacks.

Simplify this solution The Deep Dive
Marco maintains a consistent ratio between his jumping jacks and sit-ups during his workouts. On Monday, for every 3 jumping jacks, there is 1 sit-up (54:18 simplifies to 3:1). So, if Marco does 66 jumping jacks on Tuesday, using that same ratio, he will have also done \(66 / 3 = 22\) sit-ups to maintain the balance in his workout regimen. When Marco starts his workout on Wednesday with 15 sit-ups, to keep the same ratio of 3:1, he needs to do 45 jumping jacks (since \(15 \times 3 = 45\)). This way, he’s engaging the same muscles and benefiting from that coveted workout structure he loves!
