Answer 1

Step-by-step explanation:

$a) \: 0.046 \div 1000$

$\implies \: \frac{0.046}{1000}$

$\implies \: 0.000046$

$b) \: 19.20 \div 6$

$\implies \: \frac{19.20}{6}$

$\implies \: 3.20$

$c) \: 0.5 \times 10000$

$\implies \: 5000$

$d) \: 1.52 \times 19 \times 2.1$

$\implies \: 28.88 \times 2.1$

$\implies \: 60.648$

$e) \: (8.21+5)-13.5$

$\implies \: 13.21 - 13.5$

$\implies \: −0.29$

$f) \: \: 0.525+6.208+5.7$

$\implies \: 6.733 + 5.7$

$\implies \: 12.433$

$g) \: \frac{4}{5} \div \frac{7}{15}$

$\implies \: \frac{4}{ \cancel5} \times \frac{ \cancel{15}}{7}$

$\implies \: \frac{4 \times 3}{7}$

$\implies \: \frac{12}{7}$

$h) \: [9+6-12-3]÷(-48)$

$\implies \: [15-15]÷(-48)$

$\implies \: [0]÷(-48)$

$\implies \: \frac{0}{ - 48}$

$\implies \: 0$

$i) \: \frac{18}{10} \times \frac{7}{8} \times \frac{12}{49}$

$\implies \frac{ \cancel{18}}{ \cancel{10}} \times \frac{ \cancel7}{ \cancel8} \times \frac{ \cancel{12}}{ \cancel{49}}$

$\implies \: \frac{9}{5} \times \frac{1}{2} \times \frac{3}{7}$

$\implies \: \frac{27}{70}$
