Question

1. modeling real life before performing an experiment, students are asked to predict which substance will melt an ice cube the fastest. how many students make a prediction? identify the property you used.

ice cube experiment predictions
salt
sugar
water
each 😊 = 8 students.

Explanation:

Step1: Count the number of smile - y face symbols

For salt, there are 2 symbols; for sugar, there are 4 symbols; for water, there are 4 symbols. So in total, there are \(2 + 4+4=10\) symbols.

Step2: Calculate the number of students

Since each symbol represents 8 students, we multiply the total number of symbols by 8. So the number of students is \(10\times8 = 80\). The property used is multiplication.

Answer:

80 students, multiplication property.
