How to multiply decimals when not using models​

Mathematics
1 answer:
sukhopar [10]3 years ago
8 0

Answer:

You multiply it like normal numbers. But when you do, count how many numbers are behind the decimal, say there are 2 numbers behind the decimal, once you finished multiplying the numbers you would add up all the products you got and then put the first 4 numbers you wrote behind the decimal to get the final product.

Step-by-step explanation:

Say you were multiplying 14.63 and 7.74

                 

                   14.63

<u>                    x 7.74                 </u><em>Always starting from the right side of the equation</em>

                   .5852                <em>go to the left </em> <em>four digits and put a decimal then                   </em>

<em>                   ↑←←←←                just carry the decimal down and you'll  end up with  </em>

                 10.2410              <em>the final product</em>

<u>             + 102.4100                </u>

               113.2362

Please help me, I’ve literally been trying for so long.

Let the cosecutive numbers be like this :

2n + 1 , 2n + 2 , 2n + 3 , 2n + 4 , 2n + 5

Odd , Even , Odd , Even , Odd

______________________________

So we have :

(2n+1)+(2n+3)+(2n+5)=(2n+2)+(2n+4) + 39

6n + 9 = 4n + 6 + 39

6n + 9 = 4n + 45

Subtract both sides 9

6n + 9 - 9 = 4n + 45 - 9

6n + 0 = 4n + 36

6n = 4n + 36

Subtract both sides 4n

6n - 4n = 4n - 4n + 36

2n = 0 + 36

2n = 36

Divide both sides by 2

2n ÷ 2 = 36 ÷ 2

<em>n</em><em> </em><em>=</em><em> </em><em>1</em><em>8</em><em> </em>

______________________________

So the numbers are :

2(18)+1 , 2(18)+2 , 2(18)+3 , 2(18)+4 , 2(18)+5

36 + 1 , 36 + 2 , 36 + 3 , 36 + 4 , 36 + 5

37 , 38 , 39 , 40 , 41

As u can see the Odd numbers are :

37 , 39 , 41

And we're done ...

6 Mateo and Katia each walked into a
inna [77]

Answer:

(amounts could be:)

Katia: $3.50

Mateo: $1.75

Step-by-step explanation:

<em>Remember that a quarter = $0.25, 4 quarters = $1.00</em>

<h3>We know that they both have 38 quarters ($9.50) </h3>

<em>after an hour of playing games in the arcade, Katia has $1.75 more than Mateo</em>

lets say that Katia has <em>(random amount)</em><em>$3.50(14 quarters) </em>and Mateo has $1.75 less than that.

$3.50 - $1.75 = $1.75

<h3>Katia has $3.50 and Mateo has $1.75.</h3>
