Understanding the Problem in Eureka Math Lesson 38 Homework 1 1
In Eureka Math Lesson 38 Homework 1 1, students are presented with a problem that requires them to understand and apply the concept of unit rates. The problem involves calculating the total cost of purchasing a certain number of apples from a grocery store.
The problem states that the cost of purchasing 8 apples is $4. Based on this information, students need to determine the cost of purchasing 4 apples. To solve this problem, students must understand that the cost per apple is constant, regardless of the number of apples being purchased. This concept is known as a unit rate.
One way to approach this problem is to find the unit rate by dividing the total cost by the number of apples. In this case, the unit rate would be $0.50 per apple ($4 divided by 8). Once the unit rate is determined, students can use it to find the cost of purchasing 4 apples. By multiplying the unit rate by 4, they will find that the cost of purchasing 4 apples is $2.
To solve this problem successfully, students need to understand the concept of unit rates and be able to apply it in real-world scenarios. They should also be able to perform basic operations such as division and multiplication to find the solution. This problem helps students develop their mathematical reasoning and problem-solving skills.
Step-by-Step Solution for Eureka Math Lesson 38 Homework 1 1
This step-by-step solution will guide you through the process of solving Eureka Math Lesson 38 Homework 1 1. The homework involves finding the area of parallelograms and rectangles.
To find the area of a parallelogram, you need to multiply the base by the height. In this problem, the base is given as 5 units and the height is given as 8 units. Multiply the base and height together: 5 x 8 = 40. So the area of the parallelogram is 40 square units.
To find the area of a rectangle, you also multiply the base by the height. In this problem, the base is given as 10 units and the height is given as 6 units. Multiply the base and height together: 10 x 6 = 60. So the area of the rectangle is 60 square units.
To check your answers, you can use the formula for the area of a parallelogram or rectangle. For the parallelogram, the formula is base x height. For the rectangle, the formula is also base x height. Plug in the given values and see if you get the same result.
In conclusion, to find the area of a parallelogram or rectangle, multiply the base by the height. Check your answers using the appropriate formulas and ensure that you have the correct area. Remember to always label your answer with the correct unit of measurement.
