Question

Вычислите а) 1/2-1/8 ;б) -0,6-1/2

Answer 1

12-18=48-18=38

-0.6-12= -0.6-0.5=-1.1 или   -0.6-12=-610-510=-1110=-1 110

Answer 2

а)

$frac{1}{2} - frac{1}{8} = frac{4}{8} - frac{1}{8} = frac{3}{8} = 0.375$

ИЛИ

$frac{1}{2} - frac{1}{8} = 0.5 - 0.125 = 0.375$

б)

$- 0.6 - frac{1}{2} = - frac{3}{5} - frac{1}{2} = - frac{6}{10} - frac{5}{10} = - frac{11}{10} = - 1.1$

ИЛИ

$- 0.6 - frac{1}{2} = - 0.6 - 0.5 = - 1.1$
