Rounding Integer Numbers by Comparison worksheet with examples and exercises.

Let’s solve each problem step by step.

We are rounding to the nearest ten — that means we find the two tens that the number is between, then pick the one it’s closest to.

For example:
- 46 is between 40 and 50.
- 46 - 40 = 6
- 50 - 46 = 4 → so 50 is closer → circle 50 (already done in the image)

Now let’s do all the problems:

---

First Set (Round to nearest ten):

1) 46 → between 40 and 50 → 50 is closer → circle 50 ✔ (done)

2) 22 → between 20 and 30
22 - 20 = 2
30 - 22 = 8 → 20 is closer → write 20 on left, 30 on right, circle 20

3) 77 → between 70 and 80
77 - 70 = 7
80 - 77 = 3 → 80 is closer → write 70 on left, 80 on right, circle 80

4) 56 → between 50 and 60
56 - 50 = 6
60 - 56 = 4 → 60 is closer → write 50 on left, 60 on right, circle 60

5) 94 → between 90 and 100
94 - 90 = 4
100 - 94 = 6 → 90 is closer → write 90 on left, 100 on right, circle 90

6) 19 → between 10 and 20
19 - 10 = 9
20 - 19 = 1 → 20 is closer → write 10 on left, 20 on right, circle 20

7) 54 → between 50 and 60
54 - 50 = 4
60 - 54 = 6 → 50 is closer → write 50 on left, 60 on right, circle 50

8) 18 → between 10 and 20
18 - 10 = 8
20 - 18 = 2 → 20 is closer → write 10 on left, 20 on right, circle 20

9) 96 → between 90 and 100
96 - 90 = 6
100 - 96 = 4 → 100 is closer → write 90 on left, 100 on right, circle 100

10) 56 → same as #4 → between 50 and 60 → 60 is closer → write 50 on left, 60 on right, circle 60

Second Set (Round to nearest ten for bigger numbers):

1) 768 → between 760 and 770
768 - 760 = 8
770 - 768 = 2 → 770 is closer → circle 770 ✔ (done)

2) 222 → between 220 and 230
222 - 220 = 2
230 - 222 = 8 → 220 is closer → write 220 on left, 230 on right, circle 220

3) 589 → between 580 and 590
589 - 580 = 9
590 - 589 = 1 → 590 is closer → write 580 on left, 590 on right, circle 590

4) 363 → between 360 and 370
363 - 360 = 3
370 - 363 = 7 → 360 is closer → write 360 on left, 370 on right, circle 360

5) 411 → between 410 and 420
411 - 410 = 1
420 - 411 = 9 → 410 is closer → write 410 on left, 420 on right, circle 410

6) 371 → between 370 and 380
371 - 370 = 1
380 - 371 = 9 → 370 is closer → write 370 on left, 380 on right, circle 370

7) 429 → between 420 and 430
429 - 420 = 9
430 - 429 = 1 → 430 is closer → write 420 on left, 430 on right, circle 430

8) 766 → between 760 and 770
766 - 760 = 6
770 - 766 = 4 → 770 is closer → write 760 on left, 770 on right, circle 770

9) 211 → between 210 and 220
211 - 210 = 1
220 - 211 = 9 → 210 is closer → write 210 on left, 220 on right, circle 210

10) 235 → between 230 and 240
235 - 230 = 5
240 - 235 = 5 → equal distance! But rule says “round up” when exactly halfway → so circle 240

Wait — actually, standard rounding rule: if it ends in 5, round up. So yes, 235 rounds to 240.

But let’s double-check: some schools teach “round to even” for .5, but since this worksheet already rounded 46→50 and 768→770, they’re using “round half up”.

So 235 → 240.
