Question

!!!!!!!!!!ОЧЕНЬ СРОЧНО!!!!!!!!!!

Answer 1

Ответ: 1. 0.7

2/ 33.4

Объяснение:

1. 2.64/2.2-0.5 = 1.2-0.5=0.7

$=frac{264}{100} *frac{10}{22} -frac{5}{10} =frac{12}{10} -frac{5}{10} =frac{7}{10} =0.7$

2. 5.4*5.5+3.7=29.7+3.7=33.4

$=frac{54}{10} *frac{55}{10} +frac{37}{10} =frac{27}{5} *frac{11}{2} +frac{37}{10} =frac{297}{10} +frac{37}{10} =frac{334}{10} =33.4$
