Compare, order, and estimate whole numbers and decimals using place value and magnitude sense.
Compare contextual decimal quantities
Problem
\(\text{Four}\) runners finished a short race with these times: Aisha \(12.48~\text{seconds}\), Ben \(12.53~\text{seconds}\), Carlos \(12.41~\text{seconds}\), and Dana \(12.50~\text{seconds}\). Who had the fastest time?
Big Picture
What this problem is really about
The key is interpreting the context before comparing the decimals: a faster finish means less elapsed time. We’ll line up the race times by place value, find the smallest one, and use that minimum to identify the fastest runner.
