Final answer:
The base-ten block model showing 1233 represents the fraction 1233/1000 and the decimal 1.233, both of which translate to 'one and two hundred thirty-three thousandths'.
Step-by-step explanation:
The question involves understanding how to express quantities in base-ten block model formats as fractions and decimals. In base-ten, the large cube represents one whole, or 1 x 10³, which is equal to 1000. When a number is broken down into cubes, flats, rods, and units, each has a specific place value representing parts of the whole. To convert the given base-ten block model into both a fraction and a decimal, we can understand that:
- 1233 representing a thousand (1 x 10³), two hundreds (2 x 10²), three tens (3 x 10¹), and three units (3 x 10°).
- This can be expressed as the decimal 1.233, where the 1 is before the decimal point representing the thousand, and the numbers after the decimal represent the parts of the thousand: 2 hundreds (0.2), 3 tens (0.03), and 3 units (0.003).
- The equivalent fraction is 1233/1000, which literally means 1233 parts out of 1000.
- As a word representation, this is one and two hundred thirty-three thousandths.
Therefore, the correct choices would be a fraction written as 1233/1000 and as a decimal written as 1.233, and verbally expressed as one and two hundred thirty-three thousandths.
