Question

_ 3 /4 + 18 / 20 rational numbers​

Answer 1

Answer:

-3/4+18/20------17/20

Answer 2

I don't know if you want to write - 3/4 or maybe only 3/4. That's why I'm answering the both.

= - 3/4 + 18/ 20

= -3/4 + 9/10

= - 3 × 10 + 4 × 9 / 4 × 10

= - 30 + 36 / 40

= 6 / 40

= 3 / 20

= 0.165

OR

= 3 / 4 + 18 / 20

= 3 / 4 + 9 / 10

= 3 × 10 + 4 × 9 / 4 × 10

= 30 + 36 / 40

= 66 / 40

= 33 / 20

= 1.65
