Answer 1

a)240>>>12
b)16>>>12
c)960>>>12
d)48>>>12

Answer 2

a) $\frac{5}{100} * \frac{40}{100} * 600 = \frac{5*4*6}{10} = \frac{120}{10}=12$

b) $\frac{75}{100} * \frac{32}{100}*50 = \frac{3}{4} * \frac{8}{25}*50 = \frac{3}{4}*16 = 12$

c) $\frac{1,25}{100}* \frac{48}{100}*2000= \frac{1,25}{100}* 960 = 1,25*9,6 =12$

d) $\frac{25}{100}* \frac{70}{100}*68,(571428) = \frac{1}{4}* \frac{7}{10}*68,(571428)= \frac{480}{40}=12$
