Answers
Answer:
The product of two rational numbers is -7. If one of the rational number is -5, then it is easy to find the second rational number.
Step-by-step explanation:
Now lets look at it this way, a rational number is one that can be written in the form of p/q and another condition is that q is not equal to zero.
So, if one of the rational number given here is – 5, then we can say that it is equivalent to -5/1, which is the same as -5.
Now, let the second rational number be R/1.
So we know now by the equation that has been given to us as,
R/1 X -5/1 = -7/1 which is the same as writing R X -5 = -7
So, we can now write R X -5 = -7
Or we can say that -5R = -7.
Isolating –R we get, - R = -7 / 5
Or we can say that R = 7/5.
So the second rational number is 7/5
Answer:
if the product of two rational number is -4 / 3 if one of them is minus one divided by 5 find the other
