Answer:
4.5 Kg
Explanation:
Given that 500 gms of dough is required to make one sourdough loaf.
And we need 9 such loaves.
We can find the required weight of dough simply by adding 500 gms , 9 times.
i.e. 500 gms + 500 gms + 500 gms + 500 gms + 500 gms + 500 gms + 500 gms + 500 gms + 500 gms = 4500 gms.
Or we can simply multiply 500 gms by 9 to get 4500 gms.
We know that 1 kilogram = 1000 grams.
So, dividing 4500 grams by 1000 to convert into kilogram.

So, the required weight of dough for making 9 sourdough loaves is 4.5 kg.
