ПОМОГИТЕ!!

Answer 1

Ответ:

5.7 + 4.5 = 10.2
9.1 - 3.5 = 5.6
3.5 × 5.6 = 19.6
$\displaystyle9.225:4.5=\frac{9,225}{4,5}=\frac{9225}{4500} =\frac{41*225}{20*225}=\frac{41}{20}=\frac{2*20+1}{20} =2.05$

Answer 2

$5.7 + 4.5 = 10.2$

$9.1 - 3.5 = 5.6$

$3.5 \times 5.6 = 19.6$

$9.225 \div 4.5 = \frac{369}{40} \div \frac{9}{2} = \frac{369}{40} \times \frac{2}{9} = \frac{41}{20}$

или

$2.05$
