Final answer:
The ratios (14)/(35) and (4)/(10) form proportions.
Step-by-step explanation:
To determine whether the ratios form proportions, we need to set each ratio equal to the unit scale. Let's start with the first ratio, which is 14/35. To set it equal to the unit scale, we can simplify it by dividing both the numerator and denominator by 7, resulting in 2/5. This is not equal to the second ratio, 4/10, which simplifies to 2/5 as well. Therefore, the ratios do form proportions.
