Question

Please who can help me to solve this:))))

Answer 1

53.97/3 = 179.90/10
17.99 = 17.99

The price of these gourmet coffee beans are proportional, since when you divide them, they will both equal to 17.99.

Answer 2

Let the weight be "W" and the cost be "C".
We can check if they are proportional to each other by finding the constant.

W = kC
3 = k × 53.97
3 ÷ 53.97 = k
k = 0.056

Now we repeat it with the second one
W = kC
10 = k × 179.90
10 ÷ 179.90 = k
k = 0.056

The constant is the same, so yes, they are proportional.
