Taylor - 2004 Ratios compare quantities They are usually written in their simplest form. eg: Simplify the ratio 4 : 10 answer: 2 is the biggest number which goes into both of these numbers Divide each number in the ratio by 2, to give: 2 : 5 Ratios compare quantities They are usually written in their simplest form. eg: Simplify the ratio 10 : 25 answer: 5 is the biggest number which goes into both of these numbers Divide each number in the ratio by 5, to give: 2 : 5 Ratios compare quantities They are usually written in their simplest form. eg: Simplify the ratio 15 : 21 answer: 3 is the biggest number which goes into both of these numbers Divide each number in the ratio by 3, to give: 5 : 7 Ratios compare quantities They are usually written in their simplest form. eg: Simplify the ratio 8 : 18 answer: 2 is the biggest number which goes into both of these numbers Divide each number in the ratio by 2, to give: 4 : 9 Ratios compare quantities They are usually written in their simplest form. eg: Simplify the ratio 35 : 56 answer: 7 is the biggest number which goes into both of these numbers Divide each number in the ratio by 7, to give: 5 : 8 To make comparisons, we can write ratios in the form 1 : n. eg: Write the ratio 4 : 10 in the form 1 : n answer: We divide both numbers in the ratio by the first number Divide each number in the ratio by 4, to give: 1 : 2.5 To make comparisons, we can write ratios in the form 1 : n. eg: Write the ratio 3 : 21 in the form 1 : n answer: We divide both numbers in the ratio by the first number Divide each number in the ratio by 3, to give: 1 : 7 To make comparisons, we can write ratios in the form 1 : n. eg: Write the ratio 8 : 34 in the form 1 : n answer: We divide both numbers in the ratio by the first number Divide each number in the ratio by 8, to give: 1 : 4.25 To make comparisons, we can also write ratios in the form n : 1. eg: Write the ratio 4 : 10 in the form n : 1 answer: We divide both numbers in the ratio by the second number Divide each number in the ratio by 10, to give: 0.4 : 1 To make comparisons, we can also write ratios in the form n : 1. eg: Write the ratio 8 : 32 in the form n : 1 answer: We divide both numbers in the ratio by the second number Divide each number in the ratio by 32, to give: 0.25 : 1
