Para converter o número racional [tex]\(\frac{21}{25}\)[/tex] para a representação decimal, você precisa dividir o numerador pelo denominador. Vamos realizar a divisão passo a passo:

1. Nossos valores são: numerador = 21 e denominador = 25.
2. Realizando a divisão [tex]\(21 \div 25\)[/tex], obtemos o valor decimal.

Ao realizar essa divisão, nós temos:

[tex]\[ \frac{21}{25} = 0,84 \][/tex]

Portanto, a representação decimal do número racional [tex]\(\frac{21}{25}\)[/tex] é [tex]\(0,84\)[/tex].

A resposta correta é: 0,84.
