Question

(2.7-1/5):(1/2+4.5)=

Answer 1

(2,7 - 1/5) : (1/2 + 4,5) = (2,7 - 0,2) : (0,5 + 4,5) = 2,5 : 5 = 2,5 * 1/5 = 0,5

Answer 2

$(2.7 - \frac{1}{5} ) \div ( \frac{1}{2} + 4.5) =$
$= (2 \frac{7}{10} - \frac{2}{10} ) \div ( \frac{1}{2} + 4 \frac{1}{2} ) =$
$= (2 \frac{1}{2} ) \div5 =$
$= 2.5 \div 5 = 2$
