$5y - 4 \times \frac{3}{8}y + \frac{4}{5}y$
​

Answer 1

$5y - 4 \times \frac{3}{8y} + \frac{4}{5y}$

$5y - \frac{4 \times 3y}{8} + \frac{4y}{5}$

$5y - \frac{3y}{2} + \frac{4y}{5}$

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

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

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

$\frac{50y - 15y + 8y}{2 \times 5}$

$\frac{43y}{2 \times 5}$

$\frac{43y}{10}$
