Answer 2

To solve the proportion 7 1/3 : 2 1/2 = 3 2/3 : y, we can cross-multiply and solve for the unknown variable.

First, let's convert the mixed numbers into improper fractions:

7 1/3 = (7 * 3 + 1) / 3 = 22/3 2 1/2 = (2 * 2 + 1) / 2 = 5/2 3 2/3 = (3 * 3 + 2) / 3 = 11/3

Now, our proportion becomes:

(22/3) : (5/2) = (11/3) : y

To cross-multiply, we multiply the numerator of the first fraction by the denominator of the second fraction, and the numerator of the second fraction by the denominator of the first fraction:

(22/3) * y = (5/2) * (11/3)

Now, we can solve for y by multiplying both sides of the equation by 3 and dividing by 22:

y = [(5/2) * (11/3)] * (3/22)

Calculating the right side of the equation:

y = (55/6) * (3/22) y = 165/132 y = 55/44

So, the value of y is 55/44.
