(i) 7 ÷ 3.5
(ii) 36 ÷ 0 .2
(iii) 3.25 ÷ 0.5
(iv) 30.94 ÷ 0.7
(v) 0.5 ÷ 0.25
(vi) 7.75 ÷ 0.25
(vii) 76.5 ÷ 0.15
(viii) 37.8 ÷ 1.4
(ix) 2.73 ÷ 1.3
Answer :

(i) 7 ÷ 3.5 = \(\frac{7}{3.5}=\frac{70}{35}=2 \)
(ii) 36÷0.2 = \(\frac{36}{0.2}=\frac{360}{2} = 180 \)
(iii) 3.25÷0.5 = \(\frac{3.25}{0.5}=\frac{325×10}{5×100}=\frac{65}{10}=6.5 \)
(iv) 30.94÷0.7= \(\frac{30.94}{0.7}=\frac{3094×10}{7×100}=\frac{442}{10}=44.2 \)
(v) 0.5÷0.25= \(\frac{0.5}{0.25}=\frac{5×100}{25×10}=\frac{500}{250}=2 \) (vi)7.75÷0.25=\(\frac{7.75}{0.25}=\frac{775}{25}=31 \)
(vii) 76.5÷0.15= \(\frac{76.5}{0.15}=\frac{765×100}{15×10}=\frac{510}{1}= 510 \)
(viii) 37.8 ÷1.4= \(\frac{37.8}{1.4}=\frac{378}{14}=27 \)
(ix) 2.73 ÷1.3 = \(\frac{2.73}{1.3}=\frac{273×10}{13×100}=\frac{21}{10}= 2.1 \)
