Step-by-step explanation:

(i) 3/16 + 2/8

= -12+45/100

= 33/100 answer

(iii) -1/5-1/3

= 3(-1)-5*(1)/15

= -3-5/15

= -8/15 answer

Answer 2

Answer:

$\bf{(i) \frac{3}{16} + \frac{2}{8}} \\ \\ \sf {= \frac{3 + 4}{16}} \\ \\ { \boxed{ \sf{= \frac{7}{16} }}} \\ \\ \\ \bf{(ii) \frac{ - 3}{25} + \frac{9}{20} } \\ \\ \sf {= \frac{ - 12 + 45}{100} } \\ \\{ \boxed{ \sf{ = \frac{33}{100} }}} \\ \\ \bf{(iii) \frac{ - 1}{5} - \frac{1}{3} } \\ \\ \sf{= \frac{ - 3 - 5}{15} }\\ \\ { \boxed{ \sf {= \frac{ - 8}{15} }}}$
