Question

Find
Three upon five into minus four upon 7 minus two upon 28 minus four into two upon 5

Answer 1

Answer:

$-\frac{141}{70}=-2\frac{1}{70}$

Step-by-step explanation:

3 upon 5=$\frac{3}{5}$

4 upon 7=$\frac{4}{7}$

2 upon 28=$\frac{2}{28}$

2 upon 5=$\frac{2}{5}$

$\frac{3}{5}*-\frac{4}{7}-\frac{2}{28}-4*\frac{2}{5}$

$\frac{3}{5}*-\frac{4}{7}-\frac{2}{28}-4*\frac{2}{5}\\-\frac{12}{35}-\frac{2}{28}-\frac{8}{5}$

$\\-\frac{12}{35}-\frac{2}{28}-\frac{8}{5}$

$\\-\frac{12}{35}-\frac{2}{28}-\frac{8}{5}=-\frac{48}{140}-\frac{10}{140}-\frac{224}{140}$

$-\frac{48}{140}-\frac{10}{140}-\frac{224}{140}=-\frac{141}{70}=2\frac{1}{70}$
