Question

667 multiply by 21


step by step
​

Answer 1

Answer:

14007

Step-by-step explanation:

We assume, that the number 667 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 667 is 100%, so we can write it down as 667=100%.

4. We know, that x is 14% of the output value, so we can write it down as x=14%.

5. Now we have two simple equations:

1) 667=100%

2) x=14%

Answer 2

Answer:

Hence value when 667 is multiplied by 21 will be 14007

Step-by-step explanation:

In context to questions asked

We have to determine the value when 667 is multiplied by 21

So first of all we will split the given terms

As we can write 667 as 660+7

And we can write 21 as 20+1

So we can write it as,

$667 \times 21 = (660 + 7) \times (20 + 1)$

As we know that

$(a + b)(c + d) = ac + ad + bc + bd$

So we will write it as,

$(660 + 7)(20 + 1) = (660 \times 20) + (660 \times 1) + (7 \times 20) + (7 \times 1) \\ = > 13200 + 660 + 140 + 7 \\ = >14007$
