One pumpkin weighs 3.2 kilograms and a second pumpkin weighs 2.75 kilograms. how many more grams does the first pumpkin weigh?

450 grams

Step-by-step explanation:

Lots of ways to approach this. To convert kilograms to grams you multiply by 1,000 and vice Versa.

Pumpkin 1: 3.2*1000=3200 grams

Pumpkin 2: 2.75*1000=2750 grams

3200-2750=450 grams

The first pumpkin weighs 450 more grams.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

what is the answer?
