In Math, ratios are a way of comparing quantities. For example, if there are 25 girls and 20 boys in a class, the ratio is 25 : 20. Because the numbers 25 and 20 have a common factor of 5, this can be canceled down to 5 : 4, known as the simplest form.














The common factor is 50 cm. There are 3 x 50 cm in 150 cm and there are 8 x 50 cm in 4 m

A ratio such as 3:4 means 3/7 of one thing and 4/7 of another thing. The 7 comes from adding 3 and 4. The ratio 3:4 can also be written as a fraction 3/4 for calculations. In this case 900/x = 3/4 where x is the big bag of flour: so x = (4 x 900)/3. Use this method when dealing with ratios



The quantities in the ratio MUST be in the same units: in this case change the £8 to 800p


Remember the two numbers must total £85




60 ml / 3 = 20 ml and 7 x 20 ml = 140 ml
