800g : 2kg
pls tell me

2:5

Step-by-step explanation:

The ratio can be found by turning both values into either grams or kilograms. For this, I will make them both into grams.

1. 800g is already in grams, so leave it.

2. 2kg is in kilograms, and 1 kilogram = 1000 grams.

3. 2 kilograms is equal to 2000 grams.

4. For this reason, 800g: 2000g can be simplified by making 800g into 2, and 200g into 5.

That is the ratio, 2:5

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
