Jawaban:

$frac{225}{100} times frac{1}{5} - frac{70}{100} times frac{10}{28} \ = frac{45}{100} - frac{1}{4} \ = frac{45}{100} - frac{25}{100} \ frac{20}{100} = frac{1}{5}$

2,25 X $frac{1}{5}$ – 70% X $frac{10}{28}$

= $frac{225}{100}$ X $frac{1}{5}$ – 70% X $frac{10}{28}$

= $frac{225}{500}$ – 70% X $frac{10}{28}$

= $frac{225}{500}$ – $frac{70}{100}$ X $frac{10}{28}$

= $frac{225}{500}$ – $frac{700}{2800}$

= $frac{225}{500}$ – $frac{7}{28}$

= $frac{1575}{3500}$ – $frac{875}{3500}$

= $frac{700}{3500}$ = $frac{1}{5}$
