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. [tex]\frac{3}{10}+\frac{6}{10}=\frac{9}{10}[/tex]

b. [tex]\frac{1}{3}+\frac{1}{4}+\frac{1}{6}=\frac{4}{12}+\frac{3}{12}+\frac{2}{12}=\frac{9}{12}=\frac{3}{4}[/tex]

c. [tex]\frac{5}{6}-\frac{3}{6}=\frac{2}{6}=\frac{1}{3}[/tex]

d. [tex]\frac{2}{3}-\frac{6}{10}=\frac{20}{30}-\frac{18}{30}=\frac{2}{30}=\frac{1}{15}[/tex]

e. [tex]\frac{4}{10}*\frac{3}{7}=\frac{12}{70}=\frac{6}{35}[/tex]

f. [tex]\frac{1}{6}*\frac{6}{15}=\frac{1}{15}[/tex]

g. [tex]\frac{1}{8}/\frac{4}{9}=\frac{1}{8}*\frac{9}{4}=\frac{9}{32}[/tex]

h. [tex]\frac{1}{5}/\frac{3}{4}=\frac{1}{5}*\frac{4}{3}=\frac{4}{15}[/tex]

Answer with step-by-step explanation:

Reducing the given expressions to the lowest terms:

A. 3/10 + 6/10: [tex] \frac { 3 } { 10 } + \frac { 6 } { 10 } = \frac { 9 } { 10 } [/tex]

B. 1/3 + 1/4 + 1/6: [tex] \frac { 4 + 3 + 2 } { 12 } = \frac { 9 } { 12 } = \frac { 3 } { 4 } [/tex]

C. 5/6-3/6: [tex] \frac { 5 } { 6 } - \frac { 3 } { 6 } = \frac { 2 } { 6 } = \frac { 1 } { 3 } [/tex]

D. 2/3-6/10: [tex]\frac{2}{3} -\frac{6}{10} = \frac{20-18}{30} =\frac{2}{30} =\frac{1}{15}[/tex]

E. 4/10*3/7: [tex]\frac{4}{10} *\frac{3}{7} = \frac{12}{70}=\frac{6}{35}[/tex]

F. 1/6*6/15: [tex]\frac{1}{6} *\frac{6}{15} = \frac{1}{15}[/tex]

G. 1/8 divided by 4/9: [tex]\frac{\frac{1}{8} }{\frac{4}{9} } =\frac{1}{8} *\frac{9}{4} =\frac{9}{32}[/tex]

H. 1/5 divided by 3/4: [tex]\frac{\frac{1}{5} }{\frac{3}{4} } =\frac{1}{5} *\frac{4}{3} =\frac{4}{15}[/tex]
