3/7.14.1/6=

(31/7 ). (51/4 ) =

Answer 1

Respuesta:

[tex]1. - 2 \times \frac{1}{3} + \frac{1}{2} = \frac{7}{3} + \frac{1}{2} = \frac{2(7) + 3(1)}{6} = \frac{14 + 3}{6} = \frac{17}{6} = 2 \times \frac{5}{6} \\ 2. - \frac{3}{4} \times \frac{1}{5} \times \frac{10}{9} = \frac{(3)(1)(10)}{(4)(5)(9)} = \frac{30}{180} = \frac{1}{6} \\ 3. - \frac{3}{7} \times \frac{14}{1} \times \frac{1}{6} = \frac{(3)(14)(1)}{(7)(1)(6)} = \frac{42}{42} = 1 \\ 4. - \frac{31}{7} \times \frac{51}{4} = \frac{(31)(51)}{(7)(4)} = \frac{1581}{28} = 56 \times \frac{13}{28} [/tex]
