A grocer mixed 3 types of white, green and black tea in 3:5:7 ratio, respectively. How many kilograms of each are needed to make 6 kg of that mixture?

Respuesta :

Answer:

There are 6/5 white, 2 green, and 14/5 black

Step-by-step explanation:

Think of it like this.

First we add up everything.

3x+5x+7x = 6kg

15x=6

We find x and plug it in to the equation.

x=2/5

3*2/5=6/5  (6/5 is white)

5*2/5=2      (2 is green)

7*2/5=14/5   (14/5 is black)

There are 6/5 white, 2 green, and 14/5 black
