Comparing Three-Digit Numbers — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. Ana read 245 pages, Ben read 254 pages, and Cal read 225 pages. Who read the most pages?
A) Ana
B) Ben
C) Cal
D) They all read the same
Hundreds tie at 2. Tens are 4, 5, and 2, so Cal is out. Between 245 and 254, tens 5 beats 4, so Ben read the most.
2. Three boxes hold 318, 381, and 138 toys. Which box has the fewest toys?
A) 318
B) 381
C) 138
D) They are equal
318 and 381 have 3 hundreds while 138 has only 1 hundred, so the box with 138 toys has the fewest.
3. A library has 602 books, 620 books, and 260 books on three shelves. Which shelf has the most?
A) 602
B) 620
C) 260
D) They are all equal
260 has 2 hundreds, so it is out. Between 602 and 620, hundreds tie at 6 but tens 2 beats 0, so 620 is the most.
4. Which inequality chain is correct?
A) 123 < 213 < 312
B) 312 < 213 < 123
C) 213 < 123 < 312
D) 123 < 312 < 213
Hundreds digits 1, 2, and 3 order the numbers as 123 < 213 < 312, making that chain the correct least-to-greatest order.
Part B: Fill in the Blank
Write the correct answer on each line.
1. Complete: 205 < 250 < 299 (pick a number in the 200s).
Any number from 251 to 299 works; 299 is greater than 250 and still less than 300 to finish the chain.
2. Complete: 410 < 420 < 430.
Numbers 411 through 429 fit; 420 is cleanly between 410 and 430 and satisfies the chain.
3. Complete: 559 < 560 < 570.
Any number from 0 up through 559 works; 559 is just one less than 560 and keeps the chain true.
4. Complete: 700 < 750 < 800 .
Any number greater than 750 works; 800 is a clean choice that keeps 700 < 750 < 800 true.
5. Complete the chain: 301 < 310 < 315 < 320.
Any number from 311 to 319 fits; 315 is right in the middle and makes the full chain 301 < 310 < 315 < 320 true.
