Answer:4/9 and 1/64Step-by-step explanation:Do PEMDAS:ParenthesesExponentsMultiplicationDivisionAdditionSubtractionThere are no parentheses or exponents, so move onto step 3 Multiplication[tex]2 \div \frac{3}{4} \times 6[/tex][tex] \frac{3}{4} \times \frac{6}{1} = \frac{18}{4} [/tex][tex]2 \div \frac{18}{4} = \frac{2}{1} \times \frac{4}{18} = \frac{8}{18} = \frac{4}{9} [/tex]4/9 is the answer to the first problemAgain there are no parentheses or exponents, so move onto multiplication[tex] \frac{1}{2} \div 4 \times 8[/tex][tex] \frac{1}{2} \div 32 = \frac{1}{2} \times \frac{1}{32} = \frac{1}{64} [/tex]1/64 is the answer to the second problem
