Each blue box tells you what a number will round to when rounded to the nearest hundred and the nearest ten.
Drag each number below the blue box that shows how it rounds.
551
545
549
544
Nearest hundred: 500
Nearest ten: 540
Nearest hundred: 500
Nearest ten: 550
Nearest hundred: 600
Nearest ten: 550
To solve this rounding problem, let’s review how to round each number to the nearest hundred and the nearest ten.
1. 551:
– Nearest hundred: 600 (because it’s closer to 600 than to 500)
– Nearest ten: 550 (because it’s exactly halfway between 550 and 560)
2. 545:
– Nearest hundred: 500 (closer to 500 than 600)
– Nearest ten: 550 (exactly halfway between 540 and 550)
3. 549:
– Nearest hundred: 500 (closer to 500 than to 600)
– Nearest ten: 550 (exactly halfway between 540 and 550)
4. 544:
– Nearest hundred: 500 (because it’s closer to 500 than to 600)
– Nearest ten: 540 (because 544 is closer to 540 than to 550)
Now, here’s how you can drag each number into the correct blue box:
– Nearest hundred: 500, Nearest ten: 540: 544
– Nearest hundred: 500, Nearest ten: 550: 545 and 549
– Nearest hundred: 600, Nearest ten: 550: 551
This also illustrates how rounding rules apply, where numbers ending in 5 or higher round
