Question

If the weight of 12 sheets of thick paper is 40 grams, how many sheets of the same paper would weigh 3/2 kilograms

Answer 1

12sheets=40gm
Xsheets=1500gm
X=1500x12/40
X=450

Answer 2

12 sheets of thick paper is 40 g

let x be the value x sheets of thick paper is 3/2 kg
convert 3/2 kg in g 3/2×1000 =1500g
now,
12----------40
x------------1500
cross multiplication
so,
12×1500=40×x
18000=40x
x=18000÷40
x=450
