Question

Can anyone please answer my question

Answer 1

Answer:

$\frac{789}{1540}$

Step-by-step explanation:

$\frac{3}{5}$ * $\frac{2}{7}$ + $\frac{1}{7}$ * $\frac{3}{4}$ - $\frac{2}{7}$ * $\frac{-9}{11}$

= ($\frac{3}{5}$ * $\frac{2}{7}$) + ($\frac{1}{7}$ * $\frac{3}{4}$) - ($\frac{2}{7}$ * $\frac{-9}{11}$)

= $\frac{6}{35}$ + $\frac{3}{28}$ - ($\frac{-18}{77}$)

= $\frac{6}{35}$ + $\frac{3}{28}$ +$\frac{18}{77}$

= ($\frac{6}{35}$*$\frac{44}{44}$) + ($\frac{3}{28}$*$\frac{55}{55}$)+ ($\frac{18}{77}$*$\frac{20}{20}$)

= $\frac{264}{1540}$ + $\frac{165}{1540}$ + $\frac{360}{1540}$

= $\frac{264+165+360}{1540}$

= $\frac{789}{1540}$

Answer 2

$\frac{3}{5} \times \frac{2}{7} + \frac{1}{7} \times \frac{3}{4} - \frac{2}{7} \times \frac{ - 9}{11}$

$\frac{6}{35} + \frac{3}{28} - \binom{ - 18}{77}$

$\frac{6}{35} + \frac{3}{28} + \frac{18}{77}$

$\frac{6 \times 44}{35 \times 44} + \frac{3 \times 55}{28 \times 55} + \frac{18 \times 20}{77 \times 20}$

$\frac{264 + 165 + 360}{1540}$

$\frac{789}{1540}$

$= \: 0.512$
