Answer:
OR 5g : 8g
Step-by-step explanation:
Also a ratio can also be represented by a fraction; ![\frac{40g}{64g}](https://tex.z-dn.net/?f=%5Cfrac%7B40g%7D%7B64g%7D)
So to make the ratio to the simplest form we have to divide by a number that can divide both number.
40g : 64g
We can start dividing by 2 which will give us;
20g : 32g
![\frac{20g}{32g}](https://tex.z-dn.net/?f=%5Cfrac%7B20g%7D%7B32g%7D)
Now we can divide by 2 again since it can divide both numbers which will give us;
10g : 16g
![\frac{10g}{16g}](https://tex.z-dn.net/?f=%5Cfrac%7B10g%7D%7B16g%7D)
We can still divide by 2 since it can divide both numbers which will give us;
5g : 8g
![\frac{5g}{8g}](https://tex.z-dn.net/?f=%5Cfrac%7B5g%7D%7B8g%7D)
Since no numbers can divide 5 and 8 equally that is our answer.
Also, ![\frac{5g}{8g}](https://tex.z-dn.net/?f=%5Cfrac%7B5g%7D%7B8g%7D)
