Ответ:
a) 81
b) 79.38
Step-by-step explanation:
50% of 162 is half of 162. Since 50% is close to 49%, this is a good estimate. 162/2=81.
To find the exact value of 49%, I will take my estimate of 81 and subtract 1% to get 49% of 162. To find 1% I can divide 162 by 100 which is 1.62.
I subtract 81-1.62= 79.38.
