Multiply or divide as indicated. 0.07 × 0.004

검증된 단계별 안내

Identify the operation: The problem asks to multiply 0.07 by 0.004.

Rewrite the decimals as fractions to understand the multiplication better: 0.07 = \(\frac{7}{100}\) and 0.004 = \(\frac{4}{1000}\).

Multiply the fractions: \(\frac{7}{100}\) \(\times\) \(\frac{4}{1000}\) = \(\frac{7 \times 4}{100 \times 1000}\).

Calculate the numerator and denominator separately: numerator = 7 \(\times\) 4, denominator = 100 \(\times\) 1000.

Convert the resulting fraction back to a decimal by dividing the numerator by the denominator.
