Find: (i) 22% of 120

Solution:

(i) $22 \%$ of $120=\frac{22}{100} \times 120$

$=26.4$

(ii) $25 \%$ of $1000=\frac{25}{100} \times 1000$

$=250$

(iii) $25 \%$ of $10 \mathrm{~kg}=\frac{25}{100} \times 10 \mathrm{~kg}$

$=\frac{25}{10} \mathrm{~kg}=\frac{5}{2} \mathrm{~kg}$

$=2.5 \mathrm{~kg}$

(iv) $16.5 \%$ of $5000 \mathrm{~m}=\frac{16.5}{100} \times 5000 \mathrm{~m}$

$=16.5 \times 50 \mathrm{~m}$

$=825 \mathrm{~m}$

(v) $135 \%$ of $80 \mathrm{~cm}=\frac{135}{100} \times 80 \mathrm{~cm}$

$=\frac{135 \times 8}{10} \mathrm{~cm}$

$=108 \mathrm{~cm}=1.08 \mathrm{~m}$

(vi) $2.5 \%$ of $10000 \mathrm{ml}=\frac{2.5}{100} \times 10000 \mathrm{ml}$

$=250 \mathrm{ml}$
