Question

StartFraction 2 Over n EndFraction = two-thirds

a.
n = 30
c.
n = 3
b.
n = three-fourths
d.
n = 1 and one-third

Answer 1

n = 3

Explanation:

Let's consider the following proportion.

2/n = 2/3

To solve a proportion, we can use the rule that states that the product of the end-terms is equal to the products of the inner-terms. That is,

end-term × end-term = inner-term × inner-term

2 × 3 = 2 × n

6 = 2 × n

We can solve for n, dividing both terms by 2.

6/2 = 2 × n/2

n = 3
