Question

A) 2/9 × 15/8 - 1/6=
B) 2/3 : (1 - 5/9)=
C) 1/4 + 12/5 : 4/1=
D) 4/3 - 4/5 - 3/2=
E) (3/10 + 7/6) × 3/11=​

Answer 1

Respuesta:

a) $\frac{1}{4}$

b) $\frac{3}{2}$

c)$\frac{17}{12}$

d) $\frac{-29}{30}$

e)$\frac{22}{55}$

Explicación paso a paso:

a) $\frac{2}{9} X \frac{15}{8}- \frac{1}{6}$

  $\frac{30}{72} - \frac{1}{6}$

simplificado :  $\frac{5}{12} - \frac{1}{6}$

$\frac{5-2}{12}$  

$\frac{1}{4}$

b) $\frac{2}{3} : (1 - \frac{5 }{9} )$

$\frac{2}{3} : (\frac{9-5}{9} )$

$\frac{2}{3} : \frac{4}{9}$

$\frac{18}{12}$ simplifico= $\frac{3}{2}$

c)$\frac{1}{4} +\frac{12}{5} :\frac{4}{1}$

$\frac{1}{4} +\frac{12}{20} \\\\\frac{1}{4} + \frac{3}{5} \\\\\frac{5+12}{12} \\\\\frac{17}{12}$

d)

$\frac{4}{3} - \frac{4}{5} - \frac{3}{2} \\\\\frac{40-24-45}{30} \\\\\frac{-29}{30}$

e)  

$(\frac{3}{10} +\frac{7}{6} ) X \frac{3}{11} \\\\(\frac{18+70}{60} )X \frac{3}{11} \\\\\frac{88}{60} X \frac{3}{11} \\\\\frac{22}{15} X\frac{3}{11} \\\\\frac{66}{165} \\\\\frac{22}{55}$
