Question

Estimate 51% of 162.
b) Use mental math to calculate 51% of 162.

Answer 1

51% is close to 50%, or half
Half of 162 is 81. Since 51% is just 1% more than half, and 1% of 162 is approx 2, I'd say approximately 83.

Answer 2

51% is 50% + 1%, so it is half + 1%.
Half of 162 is 81.
1% of 162 is 1,62.
81+1,62=82,62. Done!
