To determine the extremes of the given proportion:
[tex]\[
\frac{4}{7} = \frac{20}{35}
\][/tex]
we need to identify the numbers that are positioned diagonally from each other when we set the two fractions equal to each other.
The extremes in the proportion [tex]\(\frac{4}{7} = \frac{20}{35}\)[/tex] are:
- The first term of the first fraction (the numerator of the first fraction), which is 4.
- The second term of the second fraction (the denominator of the second fraction), which is 35.
Thus, the extremes are the numbers 4 and 35. Hence, the correct answer is:
C. 4 and 35
