Answer 1

Answer:

Step-by-step explanation: according to your question we can state that -3 by 8 is the sum of 3 by 10 + X considering the second rational number which is unknown to us as x we can state that 3 by 10 + x is equal to minus 3 by 8 there by x is equal to minus 3 by 8- 3 by 10 full x is equal to minus 3 by 8 minus 3 by 10 finding the LCM of both the numbers which is 80

3 by 10 into 8 by 8 -3 by 8 into 8 buy it we will get minus 24 by 80 - 30 by 80 getting the answer as -54 4 by 8 therefore x is equal to 27 by 4
