Olá!

$\\ { \large \displaystyle \sf { a)\: 20\% \: \: de \: \: 1550 = }}$

${ \large \displaystyle \sf { \frac{20}{100} \cdot1550= }}$

${ \large \displaystyle \sf { 0,2 \cdot1550= }}$

$\boxed{ \boxed{ \red{{ \large \displaystyle \sf { \: 310 \: }}}}}$

$\\ { \large \displaystyle \sf { b)\: 15\% \: \: de \: \: 25620 = }}$

${ \large \displaystyle \sf { \frac{15}{100} \cdot25620= }}$

${ \large \displaystyle \sf { 0,15 \cdot25620= }}$

$\boxed{ \boxed{ \red{{ \large \displaystyle \sf { \: 3 \: 843 \: }}}}}$
