Answer 2

Verified answer

Explicación paso a paso:

Para multiplicar las dos fracciones o mas tenemos que multiplicar el línea: numerador por numerador y denominador por denominador.

Resolvamos:

a)

[tex]\frac{12}{15}\times \frac{7}{10}=\frac{12 \times 7}{15 \times 10}=\frac{84}{150} =\frac{14}{25}[/tex]

b)

[tex]\frac{6}{21}\times \frac{7}{10}\times \frac{8}{5}=\frac{6 \times 7 \times 8}{21 \times 10 \times 5}=\frac{336}{1050} =\frac{8}{25}[/tex]

c)

[tex]\frac{5}{14}\times \frac{7}{45}\times 2=\frac{5 \times 7 \times 2}{14 \times 45}=\frac{70}{630} =\frac{1}{9}[/tex]

d)

[tex]\frac{-15}{22}\times \frac{-2}{25}=\frac{-15 \times -2}{22 \times 25}=\frac{30}{550} =\frac{3}{55}[/tex]

e)

[tex]\frac{-5}{2}\times \frac{4}{25}\times 6=\frac{-5 \times 4 \times 6}{2 \times 25 }=\frac{-120}{50} =\frac{-12}{5}[/tex]

f)

[tex]-5\frac{15}{22} \times -1\frac{2}{25}=\frac{-95}{22}\times \frac{-23}{25}=\frac{-95 \times -23}{22 \times 25}=\frac{2185}{550} =\frac{437}{110}[/tex]

g)

[tex]\frac{6}{15}\times \frac{-8}{22}\times 6=\frac{6 \times -8 \times 6}{15 \times 22 }=\frac{-288}{330} =\frac{-48}{55}[/tex]

h)

[tex]\frac{-15}{22}\times \frac{2}{25}\times \frac{3}{8}=\frac{-15 \times 2 \times 3}{22 \times 25 \times 8}=\frac{-90}{4400} =\frac{-9}{440}[/tex]
