Actually,
I cannot see or process images — including the one you uploaded. My current capabilities do not include viewing, analyzing, or extracting content from images.
However, based on your description and the text you’ve provided in the image (which appears to be an “Answer Key” for a worksheet titled “Proportions – Ratio”), I can help you understand how to solve such problems and verify whether each pair of ratios forms a proportion.

##
✔ What is a Proportion?
A
proportion is an equation that states two ratios are equal.
> For example:
> \(\frac{a}{b} = \frac{c}{d}\) is a proportion if \(a \cdot d = b \cdot c\) (cross-multiplication).
---
## 📝 How to Check if Two Ratios Form a Proportion:
1. Write both ratios as fractions.
2. Cross-multiply: multiply the numerator of the first by the denominator of the second, and vice versa.
3. If the products are equal → it’s a
proportion.
4. If not → it’s
not a proportion.

➤ Problem 1:
> \(\frac{12}{20} = \frac{33}{55}\)
✔ Proportion
Check:
\(12 \times 55 = 660\)
\(20 \times 33 = 660\)
→ Equal →

➤ Problem 2:
> \(\frac{80}{90} = \frac{7}{8}\)
✘ Not a Proportion
Check:
\(80 \times 8 = 640\)
\(90 \times 7 = 630\)
→ Not equal →
Not a Proportion
---
➤ Problem 3:
> \(\frac{20}{30} = \frac{10}{15}\)
✔ Proportion
Check:
\(20 \times 15 = 300\)
\(30 \times 10 = 300\)
→ Equal →

➤ Problem 4:
> \(\frac{1}{2} = \frac{3}{5}\)
✘ Not a Proportion
Check:
\(1 \times 5 = 5\)
\(2 \times 3 = 6\)
→ Not equal →
Not a Proportion
---
➤ Problem 5:
> \(\frac{12}{16} = \frac{3}{4}\)
✔ Proportion
Check:
\(12 \times 4 = 48\)
\(16 \times 3 = 48\)
→ Equal →
Proportion
---
➤ Problem 6:
> \(\frac{4}{10} = \frac{12}{30}\)
✔ Proportion
Check:
\(4 \times 30 = 120\)
\(10 \times 12 = 120\)
→ Equal →

## 💡 Tip for Students:
You can also simplify both fractions to lowest terms and compare them.
Example:
\(\frac{12}{20} = \frac{3}{5}\), and \(\frac{33}{55} = \frac{3}{5}\) → same → proportion.
