Answer:
20 containers
Explanation:
Let us restructure the question as:
Maria needs to measure out 10 liter of broth for a recipe. If she only has a container that holds 0.5 liter, how many containers will she need to fill?
Total litre of broth measured = 10litres
If a container holds 0.5litre, then the number of container she will need will be calculated as thus:
1 container = 0.5 liter of broth
x container = 10 liters of broth
Cross multiply
0.5 * x = 1 * 10
0.5x = 10
Divide both sides by 0.5
0.5x/0.5 = 10/0.5
x = 20
Therefore she will need to fill 20 containers.
Note that the amount of liters used in question were assumed. Same calculations can be followed for any other values given.
