Answer 1

$1)2.16 \div 2.7 + 0.3 \times 1.8 =1.34 \\ 1)2.16 \div 2.7 = 0.8 \\ 2)0.3 \times 1.8 = 0.54 \\ 3)0.8 + 0.54 = 1.34$

$2)1 \frac{3}{4} \div 25 + 0.4 \times 1.9 =0.83 \\ 1 )1\frac{3}{4} \div 25 = \frac{7}{4} \times \frac{1}{25} = \frac{7}{100} =$

$= 0.07$

$2)0.4 \times 1.9 = 0.76$

$3)0.07 + 0.76 = 0.83$
