Question

add the following using sutable property as applicable b. -4/9 + -2/7 + -5/14 + 3/18​

Answer 1

Answer:

-4/9+(-2/7)+(-5/14)+3/18

= -4/9-2/7-5/14+3/18

= 3/18-4/9-2/7-5/14

=(3-4×2)/18-(2×2-5)/14

= (3-8)/18-(4-5)/14

= -5/18-(-1)/14

= -5/18+1/14

=(-5×7+1×9)/126

=(-35+9)/126

= -26/126

= -13/63
