Answer 1

Answer:

3

Step-by-step explanation:

Answer 2

Answer:

6

Step-by-step explanation:

If x/y = 2/3 and 2/x = 1/2 then x is 4 and y is 6.

from the first equation we can say x= 2 and y= 3

in the second equation - 2/x = 1/2 - the denominator, x, is twice as great as the numerator, 2. Twice 2 is 4. Thus, if x = 4, then x is 2 thirds of y, we are given the following equation to solve for y:

x = 4

2/3 * y = 4

Multiply both sides by 3/2 to eliminate the fraction on the left:

y = (3*4)/2

y = 12/2

y = 6

Thus x/y = 4/6 = 2/3, and 2/x = 2/4 = 1/2.

So y = 6.
