b. 8\left(75-50\right)+42\div \:6-15\div \left(7-2\right)8(75−50)+42÷6−15÷(7−2)
8\cdot \:25+42\div \:6-15\div \:58⋅25+42÷6−15÷5
200+42\div \:6-15\div \:5200+42÷6−15÷5
200+7-15\div \:5200+7−15÷5
200+7-3200+7−

c. \left(7,\:3+3,\:9\right)+4,\:2\cdot 3-16\div 8(7,3+3,9)+4,2⋅3−16÷8
\frac{7.3+3.9+4.2\cdot \:3-16}{8}
8
7.3+3.9+4.2⋅3−16
= \frac{7.8}{8}
8
7.8
= 0,975
d. 8\div \left(1,\:4+0,\:6\right)+4,\:2\cdot 3-1,\:68÷(1,4+0,6)+4,2⋅3−1,6
4+12.6-1.64+12.6−1.6 = 15
