How much water needs to be added to a 90 litre mixture of milk and water which is in the ratio of 2 to 1 to change the ratio to 1 to 2?
With a ratio of 2:1 there are 2 + 1 = 3 parts.Therefore 1 part of 90 litres is 90 litres ÷ 3 = 30 litres.Thus the mixture currently contains:2 parts milk → 2 × 30 litres = 60 litres of milk; and1 part water → 1 × 30 litres = 30 litres of water.The final mixture has 1 part milk to 2 parts water.This time the mixture contains 1 part of milk = 60 litres as calculated above (adding water does not change the volume of milk in the mixture, just the ratio of milk:water).Thus the amount of water in the final mixture is 2 parts = 2 × 60 litres = 120 litres.There is already 30 litres of water (as calculated above), so 120 litres - 30 litres = 90 litres of water needs to be added to the original mixture with a ratio of 2:1 to get the final mixture with a ratio of 1:2.90 litres of water needs to be added.
How do yo do ratio maths?
To share in a given ratio 1) Simplyfy the given ratio by putting each part of the ratio over the LCD 2) find the total no. of parts (add up the simplified ratio) 3) no. of parts / total no. of parts x total amount to be shared = the amout each person reacieves
If there are 77 students in the student council and the ratio of girls to boys is 7 to 4. How many girls are in the student council What is the ratio of girls to students?
With a ratio of 7:4 there are 7+4 = 11 parts - 7 parts are girls, 4 parts are boys. 77 students / 11 parts = 7 students/part Girls are 7 parts → girls = 7 students/part × 7 parts = 49 students For the ratio of girls : students, you can either use the figure just found: 49 : 77 = 7 : 11, or just go back to the original ratio: 11 parts are students, 7 of those parts are girls → ratio girls : students = 7 : 11
