(i) 4/5 ÷ 2 2/5
(ii) 2/5 + 1 1/2 - 7/9

Answer 1

Step-by-step explanation:

i) 4/5÷2 2/5

4/5÷ 12/5

4/5× 5/12

=1/3

Answer 2

Answer:

(i) 1/3 = 0.33

(ii) 101/90 = 1.12

Step-by-step explanation:

(i)

$\frac{4}{5}/ 2\frac{2}{5} \\\\\frac{4}{5}/ \frac{12}{5} \\\\(\frac{4}{5} )*(\frac{5}{12} )\\\\(\frac{1}{1} )*(\frac{1}{3} )\\\\\frac{1}{3} \\\\0.33$

(ii)

$\frac{2}{5} +1\frac{1}{2} -\frac{7}{9} \\\\\frac{2}{5} +\frac{3}{2} -\frac{7}{9} \\\\Taking LCM,\\\\\frac{18(2)+45(3)-10(7)}{90} \\\\\frac{36+135-70}{90} \\\\\frac{171-70}{90} \\\\\frac{101}{90} \\\\1.12\\\\1\frac{11}{90}$
