Question

If a = 
$\frac{ - 15}{13}$
and b =
$\frac{6}{ -7}$
find then a + (-b)​

Answer 1

$\huge\underline\mathfrak\color{blue}Answer$

A + ( - B )

=} - 15 / 13 + ( - ( - 6 ) 7 )

=} - 15 / 13 + ( + 6 / 7 )

=} - 15 / 13 + 6 / 7

=} 105 + 78 / 91

=} 183 / 91

$so \: 183 \: \div \: 91 \: is \: the \: answer$

Answer 2

${a + ( - b)} = ( \frac{ - 15}{13} + ( \frac{ 6}{ - 7} )$

=

$\frac{ - 15}{13} + \frac{ - 6}{7}$

$= \frac{ - 15}{13} + \frac{6}{7}$

$convert \: denominaters \: same$

$\frac{ - 105}{91} + \frac{78}{91}$

$\frac{ - 105 + 78}{91}$

$= \frac{ - 27}{91}$

(Decimal: -0.296703)

$hence \: verified$
