Explicație pas cu pas:
Bună !!
[tex]a) \: \frac{5}{8} \times \frac{16}{25 } = \frac{5 \times 16}{8 \times 25} = \frac{80}{200} = \frac{8}{20} = \frac{2}{5} [/tex]
[tex]b) \frac{78}{25} \div \frac{26}{5} = \frac{78}{25} \times \frac{5}{26} = \frac{78 \times 5}{25 \times 26} = \frac{390}{650} = \frac{39}{65} = \frac{3}{5} [/tex]
[tex]c) \: \: ( \frac{4}{5} ) ^{2} = \frac{16}{25} [/tex]
Sper sa fie de ajutor !!❤️
