Question

lungimea unui drum are aste de 48km.Un biciclist 1/4 din drum in prima zi ,1/2 din rest in a doua zi,iar in a yreia zi restul​

Answer 1

prima zi: 1/4din drum

$\frac{1}{4} \times 48 = \frac{1 \times 48}{4} = \frac{48}{4} = 12km \: prima \: zi$

in a 2a zi:1/2 din rest

restul este:48km-12km=36km

$\frac{1}{2} \times 36 = \frac{1 \times 36}{2} = \frac{36}{2} = 18km \: a \: doua \: zi$

48km-12km (prima zi)-18km (a doua zi)=18km a parcurs a treia zi
