$large tt = frac{2}{4} + frac{5}{5} + frac{2}{5} + 7$

$large tt = frac{1}{2} + frac{1}{1} + frac{2}{5} + 7$

$large tt = frac{1}{2} + frac{2}{2} + frac{2}{5} + 7$

$large tt = frac{1 + 2}{2} + frac{2}{5} + 7$

$large tt = frac{3}{2} + frac{2}{5} + 7$

$large tt= frac{15}{10} + frac{4}{10} + 7$

$large tt = frac{19}{10} + frac{7}{1}$

$large tt = frac{19}{10} + frac{70}{10}$

$large tt = frac{89}{10}$

$large tt = 8 frac{9}{10}$

2/4 + 5/5 + 2/5 + 7.

1 + 7 + 2/4 + 2/5.

8 + 2 x 5/4 x 5 + 2 x 4/5 x 4.

8 + 10/20 + 8/20.

8 + 18/20 = 8 9/10.
