Answer :

We need to know about ratio to solve the problem. The ratio of 350[tex]cm^{3}[/tex] to 1 litre as a ratio in its lowest terms is 7:20.

Ratio is the measure of how many times one number contains another in it. We can find the ratio of one quantity to another by dividing one by the other by cancelling out the common factors between the two. We have to find the ratio of 350[tex]cm^{3}[/tex] to 1 litre in its lowest terms. The lowest terms for both the quantities is [tex]cm^{3}[/tex]. We know that 1 litre =1000[tex]cm^{3}[/tex], we will convert the 1 litre to 1000[tex]cm^{3}[/tex] for calculating the ratio.

The ratio of 350 [tex]cm^{3}[/tex] to 1 litre =350/1000=35/100=7/20= 7:20

Therefore we found the ratio of 350 [tex]cm^{3}[/tex] to 1 litre in its lowest terms to be 7:20 by using the concept of ratio.
