you are supposed to use place value to break it down
Final answer:
To find the sum of 25+16 by breaking apart addends, you can break the numbers into tens and ones. Adding the separate tens and ones gives 30 and 11 respectively. Adding these results together, the final sum is 41.
Explanation:
The subject of your question is a fundamental mathematical concept known as addition. Specifically, you have asked to explain how to break apart the addends to find the sum of 25+16.
When we talk about 'breaking apart addends', we're referring to the strategy of making it easier to compute a big addition problem by breaking the numbers into more manageable pieces. You can usually do this by breaking numbers down into tens and ones. This is also known as 'use place value' in numerical operations.
Let's break the operation down: 25 + 16.
- First, identify the tens and ones in each addend - 25 is made up of 2 tens (20) and 5 ones, and 16 is made up of 1 ten (10) and 6 ones.
- Second, add together the tens, then add together the ones. You get 2 tens (from 25) + 1 ten (from 16) = 30, then add 5 ones (from 25) + 6 ones (from 16) = 11.
- Lastly, add these two results together. You get 30 (the sum of tens) + 11 (the sum of ones) = 41. So, the sum of 25 and 16 is 41.
Breaking apart addends helps make mental computation of these large numbers easier.

Answer and explanation:
To find : How do you write 13.8 in standard form, word form and expanded form ?
Solution :
According to place value system,
Tens Ones Tenths
1 3 8
The standard form of the number 13.8 is
The expanded form of the number 13.8 is
The word form of the number 13.8 is
13.8 = Thirteen and eight tenths.
Standard Form : 13.8 times 10^0 or just 13.8 because 10^0 is technically 1
Expanded Form : 10+3+0.8
Word Form : thirteen and eight tenths
b.if the rectangular floor has dimension of 420" by 630"
c.how many big square tiles are needed to cove rthe rectangular floor?
d.if each small tile costs P15.00 and each big tile costs P60.00which which tile should emmanuel use to econimize in tiling his floor? why?
Answers
The 8" by 7" tile covers 49 square inches.
The 21" by 21" tile covers 441 square inches.
b).
The area of the floor is (420" x 630") = 264,600 square inches.
c).
It would take (264,600) / (441) = 600 large tiles to cover the floor.
d).
Emmanuel should use the big tiles to cover his floor.
-- A big tile costs 4 times as much as a small tile, but it has 9 times
as much area as a little tile has, so it is a better buy.
-- Plus, he would have to pay the floorman a lot more to glue down 5,400 tiles
than he will have to pay to glue down only 600 tiles.
-- Since he has hired my services to advise him, I will charge him only 15%
of the difference if he takes my advice, so he will still be money ahead.

Each straw is 4-1/8 inches long.
You have one gigantic piece of straw material, 123-3/4 inches long.
How many straws can you cut it up to make ?
===> (123-3/4) divided by (4-1/8) straws.
Each one costs $0.015 to make.
So, once you find the number of short straws you have,
multiply
===> (the number of short straws) x ($0.015) .
That'll tell you how much it costs to make all of them.
Now you know how to do it on your own.
If you don't get 30 straws and $0.45 , please try again.
