Numeracy for the Hospitality Professional FIN 1371 Teresa SERRA BBA 6 & 7 Program Coordinator - Faculty 2 3 12 18 BOYS to GIRLS 1 3 4 3 1 5 1. Which is the ratio of Boys : Girls in this classroom? 2. Which is the ratio of Girls : Boys in this classroom? 3. Which is the ratio of Europeans : Asians in this classroom? 4. Which is the ratio of Asians to Europeans to Americans in this classroom? 5. Which is the ratio of Americans to Asians to Europeans in this classroom? Equivalent ratios can be formed either by multiplying or dividing each of their amounts by the same factor: Dividing each part by the same factor (Simplifying) : ▪ For example, the ratio 60 : 20 can also be written as 6 2 ▪ “6 : 2” or “6 to 2” or “ ”. (divide original ratio by 10). ▪ “30 : 10” or “30 to 10” or “ 30 ”. (divide original ratio by 2). 10 3 1 ▪ “3 : 1” or “3 to 1” or “ ”.(divide original ratio by 20). → Simplest Form Multiplying each part by the same factor : ▪ For example, the ratio 2 : 3 can also be written as 4 6 6 ▪ “6 : 9” or “6 to 9” or “ ”. (multiply original ratio by 3). 9 8 ▪ “8 : 12” or “8 to 12” or “ ”.(multiply original ratio by 4). 12 ▪ “4 : 6” or “4 to 6” or “ ”. (multiply original ratio by 2). EXERCISE 1: SHARE THESE INTO THE GIVEN RATIO X7 =35 → 4 : 2 can be simplified to its simplest terms 2 : 1 4:3 1. Add the ratio: 4 + 2 + 3 = 9 shares 2. Divide the given amount by the shares: 18 / 9 = 2 times 3. Multiply the ratio (yellow) by the times: 4 x 2 = 8 yellow marbles →
