a)
[tex]42\% \times 300 = \frac{42}{100} \times 300 = \frac{42 \times 300}{100} [/tex]
[tex]= 42 \times 3 = 126[/tex]
b)
[tex]17\% \times 1200 = \frac{17}{100} \times 1200 = \frac{17 \times 1200}{100} [/tex]
[tex] = 17 \times 12 = 204[/tex]
c)
[tex]36\% \times 500 = \frac{36}{100} \times 500 = \frac{36 \times 500}{100} [/tex]
[tex] = 36 \times 5 = 180[/tex]
d)
[tex]26\% \times 500 = \frac{26}{100} \times 500 = \frac{26 \times 500}{100} [/tex]
[tex]26 \times 5 = 130[/tex]
