which is the most expert way to estimate 32% of 79

Question

1/2 X 81

1/2 X 78

1/3 X 81

1/3 X 78

Answer 1

1/3 times 78. You up the percentage slightly and reduce the number slightly

32% to 33 1/3% is 1/3, 79 to 78

78/3 = 26

32% of 79 = 25.28

81/3 = 27

81/2 = 40.5

78/2 = 39

1/3 of 78 gives the closest estimate to 25.28
