Answer 1

Answer:

your answer is correct

Answer 2

Given:

Add or subtract the given fractions.

Solution:

$a) \: 2 \dfrac{4}{18} + \dfrac{6}{18}$

changing mixed fraction into improper fraction => 18x2+4 = 40/18

$= > \dfrac{40}{18} + \dfrac{6}{18}$

when denominators are same, add the numerators directly.

$= > \dfrac{46}{18} = \dfrac{23}{9}$

$b) \: 8 \dfrac{6}{9} - \dfrac{3}{9}$

changing mixed fraction into improper fraction => 9x8+6=78/9

$= > \dfrac{78}{9} - \dfrac{3}{9}$

when denominators are same, subtract the numerators directly.

$= > \dfrac{75}{9} = \dfrac{25}{3}$

$c) \: \dfrac{7}{8} - \dfrac{3}{8}$

when denominators are same, subtract the numerators directly.

$= > \dfrac{4}{8} = \dfrac{1}{2}$

$d) \: 10 \dfrac{4}{10} - 5 \dfrac{5}{10}$

changing mixed fraction into improper fraction => 10x10+4 = 104/10

changing mixed fraction into improper fraction => 10x5+5=55/10

$= > \dfrac{104}{10} - \dfrac{55}{10} = \dfrac{11}{2}$

when denominators are same, subtract the numerators directly.

$= > \dfrac{49}{10} = \dfrac{7}{5}$
