Answer 1

2)
266x5:100=13,3 m
3)
4km.=4000 m
4000 m..........................100%
76 m................................x %
x=76x100:4000=1,9%
4)
PLITVICE={P,L,I,T ,V ,C ,E} = 7
CROATIA={C,R,O,A,T,I) = 6
R: {I ,T}
R:7+6=13

Answer 2

2) $\frac{5}{100}*266=\frac{266*5}{100}=\frac{1330}{100}=13,3 ~m$

3) 4 km=4000 m
   400m.............100%
   76m................x%
$\frac{76*100}{4000}=\frac{7600}{4000}=1,9%$

4) Plitvice={P,L,I,T,V,E}=7 litere
     Croatia={C,R,O,A,T,I}=6 litere
     Intersectia lor ={I,T}
     6+7=13
