Desperat need steps for long division

the acronym DMSB, which stands for:

D = Divide

M = Multiply

S = Subtract  

B = Bring down

This sequence of letters can be hard to remember, so think of the acronym in the context of a family:  

Dad, Mother, Sister, Brother.

Write D M S B in the corner of your worksheet to remember the sequence you’re about to use.

How to write it down

First, you have to write down the problem in long division format. A typical division problem looks like this:

Dividend ÷ Divisor = Quotient

To write this down in long division format it looks like this:

Long division

Let’s try a fairly simple example:

65 ÷ 5 = ?

Now, let’s write that problem down in the long division format:

Long division  

We’re ready to start using the acronym: D M S B

Step 1: D for Divide

How many times will 5 go into 65? That’s too hard to work out in your head, so let’s break it down into smaller steps.

The first problem you’ll work out in this equation is how many times can you divide 5 into 6. The answer is 1. So you put 1 on the quotient line.

Step 2: M for Multiply

You multiply your answer from step 1 and your divisor: 1 x 5 = 5. You write 5 under the 6.

Long division  

Step 3: S for Subtract

Next you subtract. In this case it will be 6 – 5 = 1.

Step 4: B for Bring down

The last step in the sequence is to bring down the next number from the dividend, which in this case is 5. You write the 5 next to the 1, making the number 15.

Now you start all over again:

Step 1: D for Divide

How many times can you divide 5 into 15. The answer is 3. So you put 3 on the quotient line.

Long division  

Step 2: M for Multiply

You multiply your answer from step 1 and your divisor: 3 x 5 = 15. Write this underneath the 15.

Long division  

Step 3: S for Subtract

Now we subtract 15 from 15. 15 – 15 = 0.

There is no need for step 4. We have finished the problem.

Step-by-step explanation:

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
