Option B; (4 × 1) + (9 × 1/10) + (2 × 1/1000)

This is about expression of decimals.

  • In a decimal, when we go to the right of the decimal, the first term is usually 1/10 units, second term is usually 1/100 units, third term is usually 1/1000 units. So, the more the decimal, the more zeros at the denominator.

While the left side of the decimal, the first term is in units, second term is in tens, third term in in thousands e.t.c.

  • Applying this to the question, we have;

(4 × 1) + (9 × 1/10) + (0 × 1/100) + (2 × 1/1000)

This gives;

(4 × 1) + (9 × 1/10) + (2 × 1/1000)

Correct option is B
