Answer 1

Oie, Td Bom?!

$\frac{ \frac{3}{2} \times \frac{4}{7} - \frac{3}{14} \times 2}{ \frac{2}{3} \times \frac{3}{10} + \frac{7}{25} \times 5} + 4$

=> MDC (2).

$\frac{ 3 \times \frac{2}{7} - \frac{3}{14} \times 2}{ \frac{2}{3} \times \frac{3}{10} + \frac{7}{25} \times 5 } + 4$

=> MDC (2).

$\frac{ 3 \times \frac{2}{7} - \frac{3}{7} }{ \frac{2}{3} \times \frac{3}{10} + \frac{7}{25} \times 5 } + 4$

=> MDC (3).

$\frac{3 \times \frac{2}{7} - \frac{3}{7} }{2 \times \frac{1}{10} + \frac{7}{25} \times 5} + 4$

=> MDC (2).

$\frac{3 \times \frac{2}{7} - \frac{3}{7} }{ \frac{1}{5} + \frac{7}{25} \times 5 } + 4$

=> MDC (5).

$\frac{3 \times \frac{2}{7} - \frac{3}{7} }{ \frac{1}{5} + \frac{7}{5} } + 4$

$\frac{ \frac{6}{7} - \frac{3}{7} }{ \frac{8}{5} } + 4$

$\frac{ \frac{3}{7} }{ \frac{8}{5} } + 4$

$\frac{3}{7} \div \frac{8}{5} + 4$

$\frac{3}{7} \times \frac{5}{8} + 4$

$\frac{3 \times 5}{7 \times 8} + 4$

$\frac{15}{56} + 4$

=> MMC.

$\frac{15 + 224}{56}$

$\frac{239}{56}$
