Answer:

a. 9/10

b. 3/4

c. 1/3

d. 1/15

e. 6/35

f. 1/15

g. 9/32

h. 4/15

Step-by-step explanation:

a. $\frac{3}{10}+\frac{6}{10}=\frac{9}{10}$

b. $\frac{1}{3}+\frac{1}{4}+\frac{1}{6}=\frac{4}{12}+\frac{3}{12}+\frac{2}{12}=\frac{9}{12}=\frac{3}{4}$

c. $\frac{5}{6}-\frac{3}{6}=\frac{2}{6}=\frac{1}{3}$

d. $\frac{2}{3}-\frac{6}{10}=\frac{20}{30}-\frac{18}{30}=\frac{2}{30}=\frac{1}{15}$

e. $\frac{4}{10}*\frac{3}{7}=\frac{12}{70}=\frac{6}{35}$

f. $\frac{1}{6}*\frac{6}{15}=\frac{1}{15}$

g. $\frac{1}{8}/\frac{4}{9}=\frac{1}{8}*\frac{9}{4}=\frac{9}{32}$

h. $\frac{1}{5}/\frac{3}{4}=\frac{1}{5}*\frac{4}{3}=\frac{4}{15}$
