Answer :
To multiply \(0.2\) by \(2.1\), follow these steps:
1. Set up the multiplication:
[tex]\[ 0.2 \times 2.1 \][/tex]
2. Perform the multiplication:
[tex]\[ 0.2 \times 2.1 = 0.42000000000000004 \][/tex]
3. Match the result with the given options:
[tex]\[ F \quad 49 \\ H \quad 0.42 \\ Q \quad 4.2 \\ J \quad 0.042 \][/tex]
The detailed calculation reveals that the exact product of multiplying \(0.2\) by \(2.1\) is close to \(0.42\). Thus, the correct answer from the provided options is:
[tex]\[ \boxed{H} \][/tex]
