Just checking if the two questions are correct

63. The right answers are (a) y < 0 and (e) |y| > 1

64. Yes, you're right, answer is A. 7 1/5.

Step-by-step explanation:

Question 63.

In x * y = z, we know that x is positive, that z is negative and we know the absolute value of x is greater than the absolute value of z.

How can a positive number (x) be turned in a negative number (z) through multiplication?  By multiplying it by a negative number (y).

So, if y is negative...

we can safely say that y < 0 and that the |y| > 1.

We can say |y| > 1 because y can't equal 0 (because z > 0) and |y| can't be equal to 1 since |x| > |z|, if |y| = 1, then we'd have |x| = |z|.

Question 64.

You got your fractions addition right!

If we begin by calculating the total amount of onions the restaurant now has...

Then we split it into two equal buckets, we get...

Answer is then A.
