so i have this graph paper, and I have to draw a scale drawing of my body on it. my teacher said 3 squares is equivalent to 4 inches. so if one of my body parts, for example my head, is not a multiple of 4, how do I draw it on the paper?
I hope that makes sense.
3 squares = 4 inches, 6 = 8 etc.
for example how would I draw something that is 7 inches?
i'd like to know how to figure that out.
If your measurements are a fraction of 4 inches, make the measurement on the diagram the equivalent fraction of 3 squares.
I hope this helps. Thanks for asking.
What is the integers of multiplication
To draw a scale drawing on your graph paper, you'll need to determine the size of each square on your paper in relation to the actual measurements. In your case, your teacher mentioned that 3 squares on the paper is equivalent to 4 inches in real life.
To draw something that is 7 inches on the graph paper, you can apply the ratio you were given. Since 3 squares represent 4 inches, you can calculate the number of squares that would represent 7 inches by setting up a proportion:
3 squares / 4 inches = x squares / 7 inches
To solve for x, cross-multiply:
3 squares * 7 inches = 4 inches * x squares
21 squares = 4x
Divide both sides by 4:
21 squares / 4 = x squares
So, 5.25 squares would represent 7 inches on the graph paper. However, since you are using a grid, you'll need to decide whether to round up or down depending on the grid pattern and personal preference. In this case, you could round it to 5 or 6 squares based on the desired level of precision.
