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
What is 650 to the ratio of 5 and 8?
To find 650 in the ratio of 5:8, you first need to add the parts of the ratio (5+8=13). Then, you divide 650 by the total parts of the ratio (650/13=50). Finally, you multiply this result by the individual parts of the ratio to find the corresponding values: 550=250 and 850=400. Therefore, 650 in the ratio of 5:8 is 250:400.
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

What is 2 parts powder to one part water?
A mixture of 2 parts powder to 1 part water refers to a specific ratio used in various applications such as cooking, crafting, or industrial processes. This ratio indicates that for every 2 units of powder, 1 unit of water should be added to achieve the desired consistency or outcome. It is important to follow this ratio accurately to ensure the proper balance of ingredients and achieve the intended result.

What does mean lean mixture or rich mixture?
The ideal fuel/air mixture or ratio for most internal combustion gasoline engines is 14.7 to 1. Meaning 14.7 parts air to one part gasoline. Any ratio below this is considered a rich mixture or too much fuel. Any ratio above this is considered a lean mixture or too much air.
Is gypsum a compound or mixture?
Gypsum is a compound because it is made up of two or more elements that are chemically bonded together in a fixed ratio. In the case of gypsum, it is composed of calcium, sulfur, and oxygen atoms bonded in a specific arrangement.
What is the ideal sand to cement ratio for achieving optimal strength in a concrete mixture?
The ideal sand to cement ratio for achieving optimal strength in a concrete mixture is typically 2:1. This means using two parts sand for every one part of cement. This ratio helps to ensure a strong and durable concrete mixture.
What is a substitution for baking powder?
Bicarbonate of soda mixed with cream of tartar (this mixture is essentially what baking powder is comprised of). I believe the ratio is meant to be 1:3 bicarb to cream of tartar to make baking powder. Otherwise, there are no substitutes, but using self-raising flour may help slightly (depending on the recipe).
