Question

simplify (3/5× -35/16) +(-1/5×3/11)​

Answer 1

Answer:

$( \frac{3}{5} \times \frac{ - 35}{16} ) + ( \frac{ - 1}{5} \times \frac{3}{11} ) \\ when \: the \: multiplication \: sign \: is \: in \:the \: between \:of \: any \: to \: fractions \: we \: have \: to \: multiply \: numerator \: to \: numerator \: and \: denominator \: to \: denominator.....so \: here \: i \: did \: the \: same....\\ ( \frac{ - 105}{80} ) + ( \frac{ - 3}{55} ) \\ = \frac{ - 105}{80} + \frac{ - 3}{55} \\ now \: doing \: l.c.m \: for \: equating \: denominators .... \\ here \: l.c.m \: is \: 8870 \\ = \frac{ - 1155}{880} + \frac{ - 48}{880} = \frac{ - \: 1155 \: - \: 48}{880} \\ = \frac{ - 1203}{880} = - 1.367045$
