Question

6. Which of the following pairs represent the same rational number
-16/20 and 20/-25
​

Answer 1

Answer:

u have given only two pairs and both of them are equal to each other

-16/20 divide numerator and denominator by 4

u will get -4/5

20/-25 subtraction sign don't affect anything whether in numerator or denominator so it can written as -20/25 now divide numerator and denominator by 5 u will again get -4/5

so both of them are equal
