Question

a)Aflati 35 procente din numarul 180
b)Aflati un numar ,stiind ca 17 procente din el reprezinta 102

Answer 1

$\rm 35\%~din~180= \frac{35*18\not0}{10\not0}= \frac{630}{10}=\bold{63} \\ \\ 17\%~din~a=102 \longrightarrow \frac{17a}{100}=102 \longrightarrow 17a=10200 \longrightarrow \bold{a=600}$

Answer 2

$\frac{17}{100} *a=102=> \frac{17*a}{100}=102=>17*a=102*100=17*a=10200=>a=600$

35/100*180=25*180/100=630/10=63
