Answer:
4.5 Kg
Step-by-step 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 <em>1 kilogram = 1000 grams.</em>
So, dividing 4500 grams by 1000 to convert into kilogram.
![\Rightarrow \dfrac{4500} {1000}\\\Rightarrow 4.5 kg](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cdfrac%7B4500%7D%20%7B1000%7D%5C%5C%5CRightarrow%204.5%20kg)
So, the required weight of dough for making 9 sourdough loaves is <em>4.5 kg</em>.
