Explanation:

Step1: Solve 48 + 16 + 3

$48 + 16 + 3 = 67$

Step2: Solve $1\frac{2}{3} \times 4\frac{1}{3}$

Convert to improper fractions: $1\frac{2}{3}=\frac{5}{3}$, $4\frac{1}{3}=\frac{13}{3}$
$\frac{5}{3} \times \frac{13}{3} = \frac{65}{9} = 7\frac{2}{9}$

Step3: Solve $\frac{2}{5} \div \frac{1}{5}$

$\frac{2}{5} \times \frac{5}{1} = 2$

Step4: Solve $\frac{-936}{18}$

$\frac{-936}{18} = -52$

Step5: Solve $2\frac{1}{4} \times 3\frac{2}{3}$

Convert to improper fractions: $2\frac{1}{4}=\frac{9}{4}$, $3\frac{2}{3}=\frac{11}{3}$
$\frac{9}{4} \times \frac{11}{3} = \frac{99}{12} = \frac{33}{4} = 8\frac{1}{4}$

Step6: Solve $\frac{1}{3} \div 70$

$\frac{1}{3} \times \frac{1}{70} = \frac{1}{210}$

Step7: Solve $-63 \times -38$

$(-63) \times (-38) = 2394$

Step8: Solve $175.84 \div 11.2$

$175.84 \div 11.2 = 15.7$

Step9: Solve $\frac{20}{25} \div \frac{1}{10}$

Simplify $\frac{20}{25}=\frac{4}{5}$, then $\frac{4}{5} \times 10 = 8$

Step10: Solve $9 - 22$

$9 - 22 = -13$

Step11: Solve $108 \times -141$

$108 \times (-141) = -15228$

Step12: Solve $3.4 \times 5.2$

$3.4 \times 5.2 = 17.68$

Step13: Solve $-23 - 2 - (-8)$

$-23 - 2 + 8 = -17$

Step14: Solve $\frac{3}{10} \times \frac{4}{5}$

$\frac{3 \times 4}{10 \times 5} = \frac{12}{50} = \frac{6}{25}$

Step15: Solve $-224 \div -14$

$(-224) \div (-14) = 16$
