Final answer:
To determine whether the two ratios form a proportion, set them equal to each other and simplify. If the simplified ratios are equal, then they form a proportion.
Step-by-step explanation:
To determine whether the two ratios form a proportion, we need to set them equal to each other and simplify. The given ratios are 48/36 and 56/42.
Step 1: Set the ratios equal to each other: 48/36 = 56/42
Step 2: Simplify each ratio if possible: 48/36 = 4/3 and 56/42 = 4/3
Step 3: Compare the simplified ratios. Since both ratios are equal to 4/3, they form a proportion.
