Respuesta :
The two middle numbers are the means and outer ones are extremes.
So, in [tex]\frac{17}{50}= \frac{28}{84}[/tex] 50 and 28 are means and 17 and 84 are extremes.
Suppose we have two ratios a:b and c:d which are in proportion.
So it is written as : [tex]\frac{a}{b}=\frac{c}{d}[/tex] so 'a' and 'd' are extremes and 'b' and 'c' are means.
Answer:
these ratios are called in proportion.
Step-by-step explanation:
A proportion is a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d.
Two ratios with Four numbers a, b, c, d are in proportion if a : b = c : d (we can write it as a : b :: c : d).
On simplifying both
[tex]\frac{17}{51} \\\frac{28}{84}[/tex] gives [tex]\frac{1}{3}[/tex]
therefore these numbers are called in proportion.
