Răspuns: c = 49

Explicație pas cu pas:

aplicam probabil cunoscuta lege : produsul extremilor = produsul mezilor

a / b = c / d

extremii sunt a si d

mezii ( la mijloc) sunt  b si c  

a x d  = b x c  

in cazul prblemei date,

7 / 8 = c / 56

7 x 56 = 8 x c

c = 7 x 56 : 8 = 392 : 8 = 49

7/8 = c/56

c = 7×56/8

c = 392/8

c = 49

Ancestral characters are often preserved in an organism's developmental stages. For example, both bird and human embryos go through a stage where they have slits and arches in their necks like the gill slits and gill arches of fish. These structures are not gills and do not develop into gills in birds and humans, but because they are so simil
