2. Tommy has 100 seeds to plant in his garden. He planted 85 of the seeds. Which decimal represents the portion of the seeds Tommy has left to plant? \( \begin{array}{ll}\text { (A) } 0.85 & \text { (C) } 0.15 \\ \text { (B) } 0.5 & \text { (D) } 1.5\end{array} \)

Tommy started with 100 seeds and planted 85, which means he has 100 - 85 = 15 seeds left to plant. To convert this remaining quantity into a decimal portion, divide the seeds left (15) by the total seeds (100), which gives you 0.15. So, the correct answer is option (C) 0.15! Understanding decimal representations is crucial, as they can help you express parts of a whole in many real-world scenarios, from budgeting to measuring ingredients in recipes! For instance, if you have a cake that’s cut into 10 pieces and you eat 3, you can express that as 0.3 of the cake remaining. Keep practicing, and this skill will become second nature!
