Question

Add the following rational numbers:13/14 and -9/-7​

Answer 1

Answer:

=31/14

=23/14

Showing the Work:

Simplifying the use and arrangement of negative numbers and rewriting the equation

=1314+97

With unlike denominators find the Least Common Denominator (LCD)

LCD = 14

Multiplying numerators and denominators to get the LCD in all fraction denominators

=13/14+9×27×2

Then rewriting the equation with the equivalent fractions

=13/14+18/14

With like denominators we can operate on just the numerators

=13+18/14

=31/14

Simplifying the answer

=31/14

=23/14
