Answer:
the sum of two rational number is minus 4 by know if one of them is 13 by 6 them find the other
Step-by-step explanation:
let the second rational no. be x
then a/q,
13/6 + x = -4/9
x = -4/9 - 13/6
x = (-16 - 78)/36
x = - 94/36 or -47/18
x = -2.61111
Answer:
Student A and Student B both answered 2 questions correctly.
See explanation below
Step-by-step explanation:
Note: that answers in the form:

ARE ALL EQUIVALENT.
First of all, 4/5 is equivalent to 0.8 if we do long division.
and 19/20 is 0.95 if we do long division.
Now, <u>Student A:</u>
Both of the fractions are correct and the negative sign is equivalent and makes the answer correct, so both are correct.
For <u>Student B:</u>
Similarly, both answers are correct for this student as well, looking at the equivalence we showed first.
Also, "-" (negative) in front of the parenthesis and inside parenthesis here doesn't matter.
Hence,
Student A and Student B both answered 2 questions correctly.
