Question

2. Estimate: then find sum
1.52
+1.21.

Answer 1

Estimate: 3

Sum: 2.73

Explanation:

To find the estimate, we can round our numbers to the nearest tenth (1.52 would become 1.5, and 1.21 would become 1.2). When we add these two numbers together, we get 2.7, which can be rounded up to 3.

To find the sum, we simply add 1.52 + 1.21, which equals 2.73.
