$$\frac { 1 } { 4 } \quad 8 \frac { 7 } { 9 } 3 \frac { 2 } { 5 }$$
$\frac{1343}{180}\approx 7.461111111$
$$\frac{1}{4}\times \frac{72+7}{9}\times \frac{3\times 5+2}{5}$$
$$\frac{1}{4}\times \frac{79}{9}\times \frac{3\times 5+2}{5}$$
$$\frac{1\times 79}{4\times 9}\times \frac{3\times 5+2}{5}$$
$$\frac{79}{36}\times \frac{3\times 5+2}{5}$$
$$\frac{79}{36}\times \frac{15+2}{5}$$
$$\frac{79}{36}\times \frac{17}{5}$$
$$\frac{79\times 17}{36\times 5}$$
