A. 2/8+(10/6x6)+3/4=




B. (1/8x5/2)+(7/3x3/4)=


C. 2/3/(5/(2/4+1)-3(1/2-1/4))=

Answer 1

a)

$2 \div 8 + (10 \div 6 \times 6) + 3 \div 4 \\ 0.25 + 10 + 0.75 \\ = 11$

b)

$(1 \div 8 \times 5 \div 2) + (7 \div 3 \times 3 \div 4) \\ 0.3125 + ( \frac{7}{3} \times \frac{3}{4} ) \\ \frac{5}{16} + (7 \times \frac{1}{4} ) \\ \frac{5}{16} + \frac{7}{4} \\ \frac{33}{16}$

c)

$2 \div 3 \div (5 \div (2 \div 4 + 1) - 3((1 \div 2 - 1 \div 4)) \\ \frac{2}{3} \div (5 \div 1.5 - 3 \times 0.25) \\ \frac{2}{3} \div (5 \div \frac{3}{2} - 0.75) \\ \frac{2}{3} \div (5 \times \frac{2}{3} - \frac{3}{4} ) \\ \frac{2}{3} \div ( \frac{10}{3} - \frac{3}{4} ) \\ \frac{2}{3} \div \frac{31}{12} \\ \frac{2}{3} \times \frac{12}{31} \\ 2 \times \frac{4}{31} \\ = \frac{8}{31}$
