The Deep Dive

If you’re crafting your mathematical skills, let’s explore these ratios a bit more!
First up, we can check that (a) simplifies to 1:5, and © simplifies to approximately 2.2:1 which are not equal. However, for (b), when you convert 7.5 litres to kg based on a density, or in terms of 15 litres, you might find a proportion, so technically, that’s true! (d) indeed holds as both sides reduce to 1:2, while (e) can show a slight discrepancy based on hours travelled; they don’t match perfectly!
To dive deeper into these ratios, remember that when checking proportions, a great tip is to cross-multiply and see if both products are equal. It’s a nifty way to determine mathematical truth in ratios! Also, be careful not to get lost in the units; mismatched units can lead to incorrect conclusions faster than you can say “algebra”!
