Question

Perform the indicated operation and, if possible, simplify. Please show all of your work:
-7/12 + (-3/5)

Answer 1

= -7/12 + (-3/5) ....... Your expression
= -7/12 -3/5 ....... + * - = - (when you multiply a positive number with negative the answer is negative)
= -(7/12 + 3/5) ....... taking negative common
= -(7*5 + 12*3/12*5) ...... Adding fractions
= -(35+36/60) ....... Simplifying
= -(71/60)
= -71/60 ..... Your Answer

Answer 6

in that case we have this:
\[\Large \frac{7}{{12}} - \frac{3}{5} = \frac{{\left( {7 \cdot 5} \right) - \left( {3 \cdot 12} \right)}}{{60}} = ...?\]

Answer 7

So 7/12+(-3/5) would be worked out like this:7/12-3/5=(7•5)-(3•12)/60 =
