Steps on how to convert grams to kilograms

There are 1000 grams in 1 kilogram

For example 1/2 a kilogram is 500 Grams

2500 grams is 2.5 kilograms basically you can x kilos by 1000 and divide gramms by 1000

2.5kilos x1000 = 2500 grams

2500 divide by 1000= 2.5kilos

there are infinitely many solutions.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
