79.38

Step-by-step explanation:

We need to calculate 49% of 162 using Mental Math. 49% is 1% less than 50%.

1% in decimal form can be written as 0.01 and in fraction form can be written as 1/100.

Therefore, 1% of 162 = 0.01 x 162 = 1.62

50% is equivalent to half or 1/2.

Therefore, 50% of 162 = 81

49% = 50% - 1%

49% of 162 = (50% - 1%) of 162

49% of 162 = 50% of 162 - 1% of 162

Using the values we calculated above, we can write:

49% of 162 = 81 - 1.62

49% of 162 = 81.00 - 1.62 = 79.38
