a. 25×45 = 1.125

125:5 = 25

1.125-25 = 1.100

1.100+200 = 1.300

NOMOR 1.

$25 \times 45 - 125 \div 5 + 200$

$= 1125 - 25 + 200 = 1100 + 200 = 1300$

NOMOR 2.

$\frac{3}{5} \div \frac{1}{2} + 0.4 \times 4\%$ $= \frac{3}{5} \times \frac{2}{1} + \frac{4}{10} \times \frac{4}{100}$

$= \frac{6}{5} + \frac{16}{1000}$

$= \frac{(6 \times 200)}{(5 \times 200)} + \frac{16}{1000}$

$= \frac{1200}{1000} + \frac{16}{1000} = \frac{1216}{1000} = \frac{152}{125} = 1 \frac{27}{125}$
