Question

which number is shown by the place value blocks? choose 1 answer: a 320 b 302

Explanation:

Step1: Analyze place value blocks

Place value blocks: Each large cube (flat) represents 100, each long block (rod) represents 10, and each small cube (unit) represents 1. Here, there are 3 flats (3×100 = 300) and 2 rods (2×10 = 20). Wait, no—wait, the image: 3 large squares (each 10x10, so 100) and 2 rods (each 10 units). Wait, no, maybe I missee. Wait, the problem: the blocks—3 flats (each 100) and 2 rods (each 10)? Wait, no, the options are 320 and 302. Wait, 3 flats (3×100) + 2 rods (2×10) = 300 + 20 = 320? Wait, no, maybe the rods are units? No, place value blocks: flat is 100 (10x10), rod is 10 (10x1), unit is 1. So 3 flats: 3×100 = 300, 2 rods: 2×10 = 20. Total 300 + 20 = 320. So option A is 320.

Step2: Verify the calculation

3 (hundreds) + 2 (tens) + 0 (units) = 3×100 + 2×10 + 0×1 = 300 + 20 + 0 = 320. So the number is 320, which is option A.

Answer:

A. 320
