Answer:
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
