There are 4 brownies to share among 7 friends . How many brownies woukd each friend get ?
A) solve this problem with a diagram and with a equation .
B) describe the connections you see between the diagram and the equation
4/7
A) Solve this problem with a diagram and with an equation:
Diagram:
1. Draw 4 brownie squares.
2. Divide each brownie square into 7 equal parts.
3. Count how many parts each friend gets.
Equation:
Let x be the number of brownies each friend gets.
We need to find the value of x.
We know that there are 4 brownies to share among 7 friends, so we can set up the equation:
4 / 7 = x
B) Describe the connections you see between the diagram and the equation:
The diagram visualizes the problem by representing the 4 brownies and dividing each brownie into 7 equal parts. This helps to determine how many parts each friend gets.
The equation, on the other hand, represents the problem mathematically. It states that the number of brownies each friend gets (x) is equal to the ratio of the total number of brownies (4) divided by the total number of friends (7). Solving the equation will give us the numerical value of x, which represents the number of brownies each friend will receive.
To solve this problem, we can use both a diagram and an equation.
A) Solve the problem with a diagram:
1. Draw a rectangle to represent the 4 brownies.
2. Divide the rectangle into 7 equal parts to represent the 7 friends.
3. Count the number of brownie portions each friend receives.
B) Describe the connections between the diagram and the equation:
In the diagram, dividing the rectangle into 7 equal parts helps us visually understand how many brownie portions each friend will receive. This corresponds to the equation expressing the division: 4 (brownies) divided by 7 (friends). So, the equation is: 4 ÷ 7.
To find out how many brownies each friend will get using the equation, simply divide 4 by 7. The quotient will give you the number of brownie portions each friend receives.
Therefore, the answer is: Each friend will get (approximately) 0.57 brownies.
