Question

Does anyone know what the answer to these are

Answer 1

Answer:

1) $= 10 \frac{2}{5} = \frac{52}{5}$

2) $= \frac{252}{25} = 10 \frac{2}{25}$

Step-by-step explanation:

$6 \frac{4}{5} + 3 \frac{3}{5} \\ (6 + 3) + ( \frac{4}{5} + \frac{3}{5} ) \\ 9 + \frac{7}{5} = 9 + 1 \frac{2}{5} \\ 9 + 1 + \frac{2}{5} = 10 + \frac{2}{5}$

$\boxed{\green{= 10 \frac{2}{5} = \frac{52}{5}}}$
