Question

Four students drew models to represent 60%. Which of the following students did this correctly?

A. Student 1 drew a model representing three equal parts, shading in two of them.
B. Student 2 drew a model representing six equal parts, shading in four of them.
C. Student 3 drew a model representing five equal parts, shading in three of them.
D. Student 4 drew a model representing ten equal parts, shading in six of them.

Answer 1

Student 3 and Student 4 both correctly represented 60% by shading the correct number of parts in their diagrams: three out of five for Student 3, and six out of ten for Student 4.

Step-by-step explanation:

We're given a scenario where four students each drew models to represent 60%. Let's examine which student did it correctly:

• Student 1: Divided a model into three equal parts and shaded two. This represents × 100% = 66.67%, not 60%.
• Student 2: Divided model into six equal parts and shaded four. This is × 100% = 66.67%, which is also incorrect for 60%.
• Student 3: Divided their model into five equal parts and shaded three. So, × 100% = 60% which is correct.
• Student 4: Divided their model into ten equal parts and shaded six. Here, × 100% = 60% and this representation is also correct.

Based on the evaluation, the models drawn by Student 3 and Student 4 correctly represent 60%.
