Answer 1

3. a)
$\frac{20}{100} \times 70 = \frac{1400}{100} = 14$
b)
$\frac{14}{100} \times 250 = \frac{3500}{100} = 35$
c)
$\frac{34}{100} \times 2700 = \frac{91800}{100} = 918$
d)
$\frac{110}{100} \times 80 = \frac{8800}{100} = 88$
4.
$\frac{30}{100} \times 70 = \frac{2100}{100} = 21$
$\frac{25}{100} \times 40 = \frac{1000}{100} = 10$
$21 + 10 = 31$
