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
