Answer 2

Step-by-step explanation:

27. (d) None of these is the above.

$\frac{1}{10} + \frac{2}{5} - \frac{1}{20} \\ \\ = \frac{(2 \times 1) + (4 \times 2) - 1}{20} \\ \\ = \frac{2 + 8 - 1}{20} \\ \\ = \frac{9}{20}$

28.(a) 19.4 is the correct answer.

$1.1 \times 10 + (4.2 - 2) \times 3.7 \\ = 11 + 2.2 \times 3.7 \\ = 11 + 8.14 \\ = 19.14$
