Measures Problems

1. Whenever you have to tackle a question which has different types of units in it, it is important to make sure that you first convert all the values that are involved so that they have the same units before doing the sum.

2. If you don’t do this, the questions can get very tricky.

Example 1 :

Let’s say that we are baking a sponge cake and we need to know how much flour is in the recipe.

This is the recipe.

0.5kg plain flour

2 eggs

300g self-raising flour

100 ml of milk

400g butter

If we want to know how much flour we need in total, we would need to convert both types of flour to same units – one is in grams and the other is in kilograms.

0.5kg = 500g so we need 500g of plain flour and 300g of self-raising flour, which makes 800g of flour all together.
