Question

compare the rational numbers. -4/7 ,5/-9​

Answer 1

Answer:

-4/7, 5/-9 this is answer 5/-9 ok

Answer 2

Answer:

- FIRST TAKE LCM OF DENOMINATOR THAT IS LCM OF 7 AND 9 =63

- AFTER THIS WE MAKE DENOMINATOR EQUAL THAT IS -4/7 = -36/63 AND 5/-9 = 30/-63

- AFTER THIS WE MAKE ALL DENOMINATOR POSITIVE ITS MEANS -36/63 IS ALREADY DENOMINATOR POSITIVE NOW WE DO 30/-63 HERE DENOMINATOR IS NEGATIVE

- FOR MAKING POSITIVE WE MULTIPLY -1 THAT IS 30 * -1 AND -63 * -1 = -30/63 THE DENOMINATOR BECOME POSITIVE

- NOW WE DO COMPARE BETWEEN TWO RATION NO. THAT IS -36/63 AND -30/63

- COMPARING BY SEEN THE NUMERATOR WHICH IS GREATER

1. -36/63. 2 -30/63

- HERE -30 IS GREATER THEN -36

SO, -30/63 = 5/-9 IT IS GRATER THAN -36/63 = -4/7
