Question

-25 1\2 : (-3) + 11 9/10 : 14- 12,7 : (-10)=?

Answer 1

$1) - 25 \frac{1}{2} \div ( - 3) = - \frac{51}{2} \times ( - \frac{1}{3} ) = \\ = \frac{17}{2} = 8 \frac{1}{2} = 8.5$

$2)11 \frac{9}{10} \div 14 = \frac{119}{10} \times \frac{1}{14} = \frac{17}{20} = \\ = 0.85$

$3)- 12.7 \div ( - 10) = 1.27$

$4)8.5 + 0.85 = 9.35 \\5) 9.35 + 1.27 = 10.62$
