Step-by-step solution for: Place Value online exercise for Grade 4
Let’s solve each part step by step.
---
Part 1: Write the number using expanded form (add them up)
We just add the numbers together.
1) 700 + 50 + 8 =
→ 700 + 50 = 750 → 750 + 8 = 758
2) 100 + 60 + 2 =
→ 100 + 60 = 160 → 160 + 2 = 162
3) 400 + 90 + ? → Wait, there’s a missing number? Looking at the image, it says “400 + 90 + =” — that must be a typo. Probably meant to be “400 + 90 + 0” or maybe “+ something”. But in context, since others have three parts, and this one has only two shown, perhaps it’s 400 + 90 + 0? But let’s check the pattern. Actually, looking again — in the original image, problem 3 is written as “400 + 90 + =” with no third number. That seems like an error. But wait — maybe it’s “400 + 90 + [blank]” but the blank is for the answer? No, the instruction says “write the number using expanded form”, meaning you’re given the expanded form and you write the standard number. So if it’s “400 + 90 + =”, that doesn’t make sense unless the last term is zero. Let me recheck the image description.
Actually, in the user’s text transcription, it says:
> 3) 400 + 90 + = □
That likely means the third addend is missing — probably a typo. In many such worksheets, sometimes they omit the ones place if it’s zero. So 400 + 90 + 0 = 490. I’ll assume that.
So:
3) 400 + 90 + 0 = 490
But wait — let’s look at problem 7: “500 + 3 =” — so they do skip tens sometimes. So for #3, if it’s “400 + 90 + =”, maybe it’s implying +0? Or perhaps it’s a mistake and should be “400 + 90 + 5” or something? But since we don’t have more info, and to match the format, I think it’s safe to assume the missing part is 0. Alternatively, maybe it’s “400 + 90 + [nothing]” meaning just 490. Yes.
Similarly, problem 4: “80 + 5 =” → that’s 85, which is fine — no hundreds.
So:
3) 400 + 90 = 490 → assuming +0 → 490
4) 80 + 5 = 85
5) 900 + 70 + 7 = 900+70=970 → 970+7=977
6) 800 + 30 + 4 = 800+30=830 → 830+4=834
7) 500 + 3 = 503 (since no tens, it’s 500 + 0 + 3)
8) 600 + 10 + 3 = 600+10=610 → 610+3=613
---
Part 2: Write the correct number in the box (break down the number)
Example: 475 = 400 + 70 + 5 → so we fill in the missing part.
9) 573 = 500 + ___ + 3
→ 573 - 500 = 73; 73 - 3 = 70 → so 70
10) 826 = ___ + 20 + 6
→ 826 - 20 = 806; 806 - 6 = 800 → so 800
11) 219 = 200 + 10 + ___
→ 219 - 200 = 19; 19 - 10 = 9 → so 9
12) 357 = 300 + 50 + ___
→ 357 - 300 = 57; 57 - 50 = 7 → so 7
Wait — there are two problem 12s? In the list:
> 12) 357 = 300 + 50 + □
> 12) 702 = 700 + □ + 2
Probably a typo — the second one should be 13). Let’s call the next one 13).
13) 702 = 700 + ___ + 2
→ 702 - 700 = 2; 2 - 2 = 0 → so 0
14) 499 = 400 + ___ + 9
→ 499 - 400 = 99; 99 - 9 = 90 → so 90
---
Part 3: Fill in the correct digit for each place value
Example: 348 = 3 hundreds + 4 tens + 8 ones
So we break the number into digits by place.
15) 819 = ___ hundreds + ___ tens + ___ ones
→ 8 is hundreds, 1 is tens, 9 is ones → 8, 1, 9
16) 407 = ___ hundreds + ___ tens + ___ ones
→ 4 hundreds, 0 tens, 7 ones → 4, 0, 7
17) 539 = ___ hundreds + ___ tens + ___ ones
→ 5, 3, 9 → 5, 3, 9
18) 721 = ___ hundreds + ___ tens + ___ ones
→ 7, 2, 1 → 7, 2, 1
---
Now, let’s compile all answers carefully.
Final Answer:
1) 758
2) 162
3) 490
4) 85
5) 977
6) 834
7) 503
8) 613
9) 70
10) 800
11) 9
12) 7
13) 0
14) 90
15) 8, 1, 9
16) 4, 0, 7
17) 5, 3, 9
18) 7, 2, 1
