Odpowiedź:

[tex]1 \frac{1}{8} \times (4 \frac{3}{5} - 2 \frac{7}{10} ) + {( \frac{1}{2}) }^{3} = \frac{9}{8} \times (4 \frac{6}{10} - 2 \frac{7}{10} ) + \frac{1}{8} = \frac{9}{8} \times 1 \frac{9}{10} + \frac{1}{8} = \frac{9}{8} \times \frac{19}{10} + \frac{1}{8} = \frac{171}{80} + \frac{1}{8} = \frac{171}{80} + \frac{10}{80} = \frac{181}{80} = 2 \frac{21}{80} [/tex]

Odpowiedź:

1 1/8 • ( 4 3/5 - 2 7/10 ) + ( 1/2 )³ = ​9/8 * (4 6/10 - 2 7/10) + 1/8 =

= 9/8 * (3 16/10 - 2 7/10) + 1/8 = 9/8 * 1 9/10 + 1/8 = 9/8 * 19/10 + 1/8 = 171/80 + 1/8 = 2 11/80 + 10/80 = 2 21/80
