Question

Georgie needs to paint the wall with a fixing mixture.
She mixes glue and water in the ratio 3:1 to make the mixture.
Georgie needs 5 litres of the mixture.
She has 3.5 litres of glue. Does Georgie have enough glue to make 5 litres of the mixture?

Answer 1

To determine if 3.5 liters of glue will be enough, you can set up a proportion using the ratio of glue to water (3:1).

3 L glue    3.5 L glue
1 L water =  x L water

Use cross products to solve for the amount of water.

3x = 3.5
3      3

x = 1.17 L

You will need approximately 1.17 L of water with 3.5 L of glue.  This is a total of 4.67 L, which is NOT enough.

You will not be able to make the mixture.

Answer 2
