Answer:
4 and 35
Explanation:
ratios can be written as fractions, and fractions can therefore be written as ratios, so we can rewrite this equation as such:
4/7 = 20/35
4 : 7 = 20 : 35
we know now that 4 and 35 are extremes (first/last terms of equation; outer most terms of ratio) and 7 and 20 are the means (inner most terms of equation)
so, the extremes are 4 and 35.
hope this helps!!
