Question

$\sqrt{ \frac{1}{4} } \times \sqrt{ \frac{4}{36 } } + \frac{5}{12} \times \frac{18}{5}$
cuanto es ?​

Answer 1

Respuesta:

$\frac{5}{3}$

Explicación paso a paso:

$\sqrt{\frac{1}{4}}\cdot \sqrt{\frac{4}{36}}+\frac{5}{12}\cdot \frac{18}{5}$

• $\sqrt{\frac{1}{4}}\sqrt{\frac{4}{36}}=\frac{1}{2}\sqrt{\frac{4}{36}}=\frac{1}{2}\cdot \frac{1}{3}=\frac{1}{2\cdot \:3}=\frac{1}{6}$

• $\frac{5}{12}\cdot \frac{18}{5}=\frac{5\cdot \:18}{12\cdot \:5}=\frac{18}{12}=\frac{3}{2}$

$=\frac{1}{6}+\frac{3}{2}$

MCM de 6 y 2:

06-02 l 2

03-01  l 3

01-01  l

MCM = 2x3 = 6

$\frac{3}{2}=\frac{3\cdot \:3}{2\cdot \:3}=\frac{9}{6}$

$\frac{1}{6}+\frac{9}{6}=\frac{1+9}{6}=\frac{1+9}{6}=\frac{5}{3}$

Answer 2

Respuesta:

\frac{5}{3}

Explicación paso a paso:

\sqrt{\frac{1}{4}}\cdot \sqrt{\frac{4}{36}}+\frac{5}{12}\cdot \frac{18}{5}

\sqrt{\frac{1}{4}}\sqrt{\frac{4}{36}}=\frac{1}{2}\sqrt{\frac{4}{36}}=\frac{1}{2}\cdot \frac{1}{3}=\frac{1}{2\cdot \:3}=\frac{1}{6}

\frac{5}{12}\cdot \frac{18}{5}=\frac{5\cdot \:18}{12\cdot \:5}=\frac{18}{12}=\frac{3}{2}

=\frac{1}{6}+\frac{3}{2}

MCM de 6 y 2:

06-02 l 2

03-01  l 3

01-01  l

MCM = 2x3 = 6

\frac{3}{2}=\frac{3\cdot \:3}{2\cdot \:3}=\frac{9}{6}

\frac{1}{6}+\frac{9}{6}=\frac{1+9}{6}=\frac{1+9}{6}=\frac{5}{3}
