Question

¡avanza! goal: talk about family and ages. 1 escribe los números de las siguientes operaciones matemáticas en palabras! modelo: 400 + 800 = 1.200 cuatrocientos más ochocientos son mil doscientos. 1. 300 + 200 = 500 2. 800 − 100 = 700 3. 600 + 400 = 1.000 4. 900.000 + 100.000 = 1.000.000 5. 1.300 − 200 = 1.100

Explanation:

To solve this, we need to describe each mathematical operation in Spanish words following the given model. Let's go through each one:

1. \( 300 + 200 = 500 \)

• First, identify the numbers: 300 is "trescientos", 200 is "doscientos", and 500 is "quinientos".
• The operation is addition ("más").
• So we say: "Trescientos más doscientos son quinientos."

2. \( 800 - 100 = 700 \)

• 800 is "ochocientos", 100 is "cien" (or "ciento" but in this context "cien" is used for subtraction here), and 700 is "setecientos".
• The operation is subtraction ("menos").
• So we say: "Ochocientos menos cien son setecientos."

3. \( 600 + 400 = 1000 \)

• 600 is "seiscientos", 400 is "cuatrocientos", and 1000 is "mil".
• The operation is addition ("más").
• So we say: "Seiscientos más cuatrocientos son mil."

4. \( 900000 + 100000 = 1000000 \)

• 900000 is "novecientos mil", 100000 is "cien mil", and 1000000 is "un millón".
• The operation is addition ("más").
• So we say: "Novecientos mil más cien mil son un millón."

5. \( 1300 - 200 = 1100 \)

• 1300 is "mil trescientos", 200 is "doscientos", and 1100 is "mil ciento".
• The operation is subtraction ("menos").
• So we say: "Mil trescientos menos doscientos son mil ciento."

• The operation is subtraction ("menos").
• So we say: "Mil trescientos menos doscientos son mil ciento."
