Explain how modeling partial products can be used to find the products of greater numbers ?
1 answer:
You can break large numbers into a sum of a multiple(s) of 10 and the last digit of the number. For example, you can break 26 as 20+6, or 157 as 100+50+7.
Then, using the distributive property, you can turn the original multiplication into a sum of easier multiplications. For example, suppose we want to multiply 26 and 37. This is quite challenging to do in your mind, but you can break the numbers as we said above:
All these multiplications are rather easy, because they either involve multiples of 10 of single-digit numbers:

Step-by-step explanation:
We have the four thickest books from the line plot given by
Two books of inch thick and the two books of
inch thickness.
So when the two inch thick book is being piled on the top of a
inch thick books.
Therefore, the total thickness of the pile of books is given by :
Therefore, the thickness of the pile is .
<h2>Answer:</h2>
The first consecutive odd number is: 9
and the second consecutive odd number is: 11
<h2>Step-by-step explanation:</h2>Let the two consecutive odd numbers be: a and a+2
( Since, we know that the difference between two consecutive odd or two consecutive even numbers is always 2 )
Now, it is given that:
Three times the first is 5 more than twice the second.
i.e.
Hence, we get:
The first consecutive odd number is: 9
and the second consecutive odd number is: 9+2=11
