Question

(8,2-5,42):3,5+2,4:0,25+5(6)=

Answer 1

2,78:3,5+9,6+$\frac{56-5}{9}$=$\frac{278}{100}$*$\frac{35}{10}$+$\frac{96}{10}$+$\frac{51}{9}$=$\frac{973}{100}$+$\frac{960}{100}$+$\frac{51}{9}$=$\frac{1933}{100} +\frac{51}{9}$=$\frac{17397+5100}{900}$=$\frac{22497}{900}$=$\frac{7499}{300}$

Answer 2

(82/10-542/100): 35/10+24/10:25/100+51/9=


= 278/100 • 10/35 + 24/10 • 100/25 +51/9


=278/10•35 + 24• 10/25 + 51/9


= 9730/10 + 240/25 + 51/9


= 973 + 48/5 + 51/9


= 973 + 48/5 + 17/3

= 973 + 144/15 + 85/ 15

=973 + 229/15
