Marks: +1, -0

The value of 3.5 × 2.4 × 4.8 is :

Solution:

Concept:

Convert decimals to fractions and multiply step by step to get the exact fractional value.

Explanation:

Write each decimal as a fraction:

3.5 = \frac{35}{10}

2.4 = \frac{24}{10}

4.8 = \frac{48}{10}

Multiply the numerators and denominators:

\frac{35 \times 24 \times 48}{10 \times 10 \times 10}

Simplify by canceling common factors:

\frac{35}{10} = \frac{7}{2}

\frac{24}{10} = \frac{12}{5}

\frac{48}{10} = \frac{24}{5}

Now multiply:

\frac{7}{2} \times \frac{12}{5} \times \frac{24}{5}

Cancel 2 from denominator with 12:

\frac{7}{1} \times \frac{6}{5} \times \frac{24}{5} = \frac{7 \times 6 \times 24}{5 \times 5}

Compute numerator:

7 \times 6 = 42

42 \times 24 = 1008

. Denominator:

5 \times 5 = 25

Thus the product is

\frac{1008}{25}

Answer:

\frac{1008}{25}
