Answer 2

Subtracting $\frac{9}{17}$ from $-\frac{12}{5} ,$ results in $-2\frac{79}{85} .$

Given,

Two fractions:

$\frac{9}{17},$ and $-\frac{12}{5} .$

To find,

Subtract $\frac{9}{17}$ from $-\frac{12}{5} .$

Solution,

It can be seen that the 2 fractions are given here, which are

1st: $\frac{9}{17},$ and

2nd: $-\frac{12}{5} .$

We have to subtract fraction 1st from 2nd. It means we have to find,

$-\frac{12}{5} -\frac{9}{17}.$

Now, the LCM of 5 and 17 is 85. So, the difference can be determined as follows.

$-\frac{12 \times 17 }{5 \times 17} -\frac{9 \times 5}{17 \times 5}$

$=-(\frac{12 \times 17 }{5 \times 17} +\frac{9 \times 5}{17 \times 5})$

$=-(\frac{12 \times 17 + 9 \times 5}{85} )$

$=-(\frac{204 + 45 }{85} )$

$=-(\frac{249 }{85} )$

$=-\frac{249 }{85}$

$=-2\frac{79}{85} .$

So, on subtracting $\frac{9}{17}$ from $-\frac{12}{5} ,$ we get $-2\frac{79}{85} .$

Therefore, subtracting $\frac{9}{17}$ from $-\frac{12}{5} ,$ results in $-2\frac{79}{85} .$
