Actually, this image is
not about identifying whether meat is fresh or not — that’s a playful trick in the title! The real topic is
“Solving Problems Involving Scale Drawings of Geometric Figures”, as stated at the bottom.
The “MEAT SECTION” and “fresh or not” are just humorous labels. You’re being asked to evaluate
6 statements about scale drawings, ratios, and proportions and label each as
True (T) or
False (F).
Let’s go through each one:
---
1. A scale ratio is the comparison of two quantities with different units.
✔ FALSE
> A
scale ratio compares two quantities
with the same unit — it’s a dimensionless ratio. For example, 1:100 means 1 cm on the drawing = 100 cm in real life. The units cancel out when you write the ratio. If the units are different (e.g., cm to meters), you must convert them first to be the same before forming the ratio.
---
2. Scale drawing is only used to reduce an actual object while keeping it proportionally the same.
✔ FALSE
> Scale drawings can be used to
reduce OR enlarge objects. For example, engineers might use a scale of 2:1 to draw a small mechanical part larger so they can see details clearly. So it’s not “only used to reduce.”
---
3. Scale drawing is used by architects and engineers in planning and building their projects.
✔ TRUE
> This is correct. Architects use floor plans (scale drawings) to design buildings. Engineers use scaled blueprints for bridges, machines, etc. It’s essential for accurate construction.
---
4. The concept of ratio and proportion is used to solve for the actual dimension of an object.
✔ TRUE
> Yes — if you know the scale (e.g., 1:50) and the measurement on the drawing, you multiply by the scale factor to find the actual size. That’s using proportion:
> *Drawing length / Actual length = 1 / 50*
---
5. 10:13 is an example of ratio.
✔ TRUE
> A ratio is simply a comparison of two numbers. 10:13 is a valid ratio — it doesn’t need to simplify or represent anything physical to be a ratio.
---
6. The ratio of the length of two corresponding sides of two similar geometric figures is called scale factor.
✔ TRUE
> Exactly. When two figures are similar, their corresponding sides are proportional. The constant ratio between any pair of corresponding sides is called the
scale factor.

Note: The “meat” theme is just for fun — it’s a math worksheet disguised as a butcher shop! 😄
