(b)=25/4+(-11/4)
(c)=18/-5+62/4
(d)=9/10+(-46/5)​

Answer 1

a)  $\frac{27}{20}+15=16\frac{7}{20}$

b)  $\frac{25}{4}+(\frac{-11}{4})=3\frac{1}{2}$

c)  $\frac{18}{-5}+\frac{62}{4}=11\frac{9}{10}$

d)  $\frac{9}{10}+(\frac{-46}{5})=-8\frac{3}{10}$

Step-by-step explanation:

To find : The following sums and express your answer as mixed fraction ?

Solution :

a) $\frac{27}{20}+15$

$\frac{27}{20}+15=\frac{27+20\times 15}{20}$

$\frac{27}{20}+15=\frac{27+300}{20}$

$\frac{27}{20}+15=\frac{327}{20}$

$\frac{27}{20}+15=16\frac{7}{20}$

b) $\frac{25}{4}+(\frac{-11}{4})$

$\frac{25}{4}+(\frac{-11}{4})=\frac{25-11}{4}$

$\frac{25}{4}+(\frac{-11}{4})=\frac{14}{4}$

$\frac{25}{4}+(\frac{-11}{4})=\frac{7}{2}$

$\frac{25}{4}+(\frac{-11}{4})=3\frac{1}{2}$

c) $\frac{18}{-5}+\frac{62}{4}$

$\frac{18}{-5}+\frac{62}{4}=\frac{-72+310}{20}$

$\frac{18}{-5}+\frac{62}{4}=\frac{238}{20}$

$\frac{18}{-5}+\frac{62}{4}=\frac{119}{10}$

$\frac{18}{-5}+\frac{62}{4}=11\frac{9}{10}$

d) $\frac{9}{10}+(\frac{-46}{5})$

$\frac{9}{10}+(\frac{-46}{5})=\frac{45-460}{50}$

$\frac{9}{10}+(\frac{-46}{5})=\frac{-415}{50}$

$\frac{9}{10}+(\frac{-46}{5})=\frac{-83}{10}$

$\frac{9}{10}+(\frac{-46}{5})=-8\frac{3}{10}$
