Answer 2

Explicación paso a paso:

III. A: 2/18 = 1/9

B: 5/18

C: 7/18

D: 9/18 = 1/2

E: 12/18 = 2/3

F: 17/18

IV: a.

$\frac{1}{9} \times \frac{2}{3} = \frac{2}{27}$

b.

$\frac{2}{3} - ( - \frac{2}{9} ) \\ \frac{2}{3} + \frac{2}{9} \\ \frac{6}{9} + \frac{2}{9} = \frac{8}{9}$

c.

$( \frac{2}{10} - ( \frac{5}{2} \div \frac{12 - 1}{9} )) \\ ( \frac{1}{5} - ( \frac{5}{2} \times \frac{9}{11} )) \\ ( \frac{1}{5} - \frac{45}{22} ) = - \frac{203}{110}$

d.

$1 - \frac{4}{5} + \frac{5}{9} \\ \frac{1}{5} + \frac{5}{9} = \frac{34}{45}$

V.

a.

$1.5 + 1.9 + 0.7 =4.1 \\ 4.1 \times 5 = 20.5 km$

b.

$\frac{21}{2} \div \frac{6}{9} \\ \frac{21}{2} \times \frac{9}{6} \\ \frac{189}{12} = 15.75$
