19. James mide 138 centímetros de alto. Una jirafa mide 4 metros y 5 centímetros de alto. ¿Cuánto más alta es la jirafa que James?

20. La Sra. Smith tiene un listón rojo y un listón azul. El listón rojo mide 9 metros y 60 centímetros de largo. El listón azul mide 264 centímetros de largo. ¿Cuál es la longitud total de ambos listones?

Sure! Let's solve each problem step by step using the "Lee-Dibuja-Escribe" (Read-Draw-Write) process.

Problem 19:
- Read: James is 138 centimeters tall. A giraffe is 4 meters and 5 centimeters tall. We need to find out how much taller the giraffe is compared to James.

- Draw: Visualize the heights, where James is 138 cm, and the giraffe is 4 meters 5 centimeters. We can convert both measurements to the same units for easier comparison.

- Write:
1. Convert the giraffe’s height to centimeters. There are 100 centimeters in a meter, so:
- 4 meters = 4 × 100 = 400 cm
- Adding the 5 extra centimeters: 400 cm + 5 cm = 405 cm
2. Subtract James's height from the giraffe's height to find the difference:
- 405 cm (giraffe) - 138 cm (James) = 267 cm

So, the giraffe is 267 centimeters taller than James.

Problem 20:
- Read: The red ribbon is 9 meters 60 centimeters long, and the blue ribbon is 264 centimeters long. We need to find the total length of both ribbons.

- Draw: Think of two ribbons, one longer than the other. Both need to be measured in the same units for addition.

- Write:
1. Convert the red ribbon's length to centimeters. Again, 1 meter = 100 centimeters:
- 9 meters = 9 × 100 = 900 cm
- Adding the 60 extra centimeters: 900 cm + 60 cm = 960 cm
2. Add the lengths of both ribbons together:
- 960 cm (red ribbon) + 264 cm (blue ribbon) = 1224 cm

The total length of both ribbons is 1224 centimeters.

I hope this helps! If you have any more questions, feel free to ask.
