Which is the most accurate way to estimate 52% of 71?

Step-by-step explanation:

You might take 50% of 70, which would give you 35: 0.50 (70) = 35

If you want greater accuracy, multiply 0.52 by 70 instead of 71:

0.52 (70) = 36.4. (It's less work than multiplying 0.52 by 71).

Actual value: 0.52 (71) = 36.92
