Question

The weight of 45 cartons is 405kg. Find the weight of 73 cartons​

Answer 1

You can set this problem up as an equivalent ratio:
45 cartons/405 kg = 73 cartons/x kg

Then, you would have to cross-multiply by doing:
73*405 = 45*x
29565=45x
x=657 kg

Answer 2

657kg

Explanation:

405 ÷ 45 = 9

9 x 73 = 657kg

I hope this helps!
