7 0

Answer:

29 approximately

Step-by-step explanation:

You want to estimate 35% of 84. 35% is roughly equivalent to 1/3, so multiply 84 by 1/3 (or, equivalently, divide 84 by 3), obtaining 28. Use a calculator to find 0.35(84): 29.4. This 28 is a fairly good estimate of 35% of 84 which is 29.4.
