When you divide which number goes first
Next, we look at how many times 3 goes into Using the multiplication table if needed we can see that 3 goes into 12 exactly 4 times with no remainder. The original recipe calls for 3 eggs and we again divide by 3.
Next the recipe calls for 1tsp teaspoon of vanilla extract. We need to divide one teaspoon by 3. We can look at this another way, if we know that one teaspoon is the same as 5ml or 5 millilitres. If you need some help with units, see our page on Systems of Measurement.
If we want to be more accurate, we can try dividing 5ml by 3. We can use our estimating skills and say that one teaspoon divided by three is a tiny bit more than one and a half ml. If you have some of those tiny measuring spoons in your kitchen, you can be super-accurate! We can estimate the answer, to check that we are correct. Three lots of 1. Recipes are rarely an exact science, so a little bit of estimating can be fun and good practice for our mental arithmetic.
Next the recipe calls for 1—2 tbsp of milk. That is between 1 and 2 tablespoons of milk. We have no definitive amount and how much milk you add will be dependent on your mixture consistency. One tablespoon is the same as 15ml. This eBook provides worked examples and easy-to-understand explanations to show you how to use basic mathematical operations and start to manipulate numbers.
It also includes real-world examples to make clear how these concepts are useful in real life. Whether you want to brush up on your basics, or help your children with their learning, this is the book for you.

Have students model and solve the three problems below: 1 Eva has 3 plates. She puts 5 cookies on each plate. How many cookies does Eva have? Next have the students work the following problems: Tell what is unknown in each problem. Then solve the problem. There are 7 students at each center. Quotient is always written above the line and product below the number of dividend.

Subtract the number you just wrote below the dividend from the digits of the dividend directly above it. Write the result beneath the line you just drew.
Do not subtract from the complete dividend, but only those digits you worked with in Parts One and Two. In the example, you should not subtract 24 from Bring down the next digit. Write the next digit of the dividend after the result of your subtraction operation. In this case, you'll grab the 0 from and place it after the 1, making it 10, which 6 can go into. Repeat the whole process. Divide the new number by your divisor, and write the result above the dividend as the next digit of the quotient.
Write that number 1 into the quotient above the dividend. Then multiply 6 by 1, and subtract the result from You should end up with 4. If your dividend has more than three digits, keep repeating this process until you've worked through all of them. For example, if we we had started with 2, grams Part 4.
Record the remainder. Depending on what you're using this division for, you may want to finish up with a quotient that's a whole number, with a remainder, i. Place your remainder after the quotient with a letter "r" before it.
In the example, the answer would be expressed as "41 r4. In a case such as this, it would not be useful think about things in terms of partial cars or partial people. If you plan to calculate a decimal, you can skip this step.
Add a decimal point. If you are planning to calculate a precise answer rather than one with a remainder, you'll now need to move beyond whole numbers. When you've reached a point at which you are left with a number smaller than your divisor, add a decimal point to both the quotient and the dividend. In the example, since is a whole number, every digit after the decimal will be 0, making it Keep repeating. Now you have more digits that can be brought down all of them zeroes.
Bring down a zero and continue as before, determining how many times the divisor can go into the new number. Add that number 6 to the quotient above the dividend and after the decimal point. Then multiply 6 by 6, and subtract the result from You should end up with 4 again. Stop and round. In some cases, you will find that when you start to solve for the decimal, the answer repeats over and over.
At this point, it's time to stop and round your answer up if the repeating number is 5 or greater or down if it is 4 or less. In the example, you could keep getting 4 out of forever, and add 6's to your quotient indefinitely.
Instead of doing this, stop the problem and round the quotient. Because 6 is greater than or equal to 5, you would round up to Alternatively, you can indicate a repeating decimal by placing a small horizontal line over the repeating digit.
In the example, this would make the quotient Add the unit back to your answer. If you are working with units like pounds, gallons, or degrees, once you are done with all your calculations, add the unit to the end of your answer.
