School homework about multiplying fractions <br><br>worth 30 brainly points​
RoseWind [281]

Answer:

Explanation:

1. \frac{1}{3} x \frac{6}{7} = \frac{6}{21}

          = \frac{2}{7}

b. \frac{6}{8} + \frac{4}{9} = \frac{24}{72}

            = \frac{1}{3}

c. \frac{10}{15} x \frac{3}{4} = \frac{30}{60}

            = \frac{1}{2}

d. \frac{7}{10} of \frac{5}{10} = \frac{7}{10} x \frac{5}{10}

                = \frac{35}{100}

                = \frac{7}{20}

e. \frac{3}{8} of \frac{4}{6} = \frac{3}{8} x \frac{4}{6}

            = \frac{12}{48}

            = \frac{1}{4}

f. \frac{7}{12} of \frac{9}{14} = \frac{7}{12} x \frac{9}{14}

              = \frac{63}{168}

              = \frac{3}{8}

2. \frac{22}{6} x \frac{3}{11} = \frac{66}{66}

              = 1

b. \frac{15}{6} x \frac{4}{5} = \frac{60}{30}

             = 2

c. \frac{25}{8} x \frac{4}{10} = \frac{100}{80}

              = \frac{5}{4}

d. \frac{33}{12} x \frac{4}{15} = \frac{132}{180}

             = \frac{11}{15}

A chemical reaction is a reaction in which two or more species combine together to form a molecule with a new chemical composition.

In a chemical reaction, the reactants are written on left hand side pointing a forward arrow towards the products which are written on the right hand side.

For example, chemical reaction between hydrogen and oxygen will result in the formation of water. The reaction equation will be as follows.

          2H_{2} + O_{2} \rightarrow 2H_{2}O
