Evaluate the following and express the answer as a decimal.
$1.4 \times 0.12$
To do: Evaluate the expression as decimal
Solution:
$1.4 \times 0.12$
1.4 can be written as $\frac{14}{ 10}$ [ fraction after one point from right end, so divide by 10]
0.12 can be written as $\frac{12}{ 100}$ [ fraction after two numbers from right end, so divide by 100]
multiply now,
$\frac{14}{ 10} \times \frac{12}{ 100}$
Multiply numerators and denominators individually,
$\frac{14 \times 12}{10 \times 100}$
$\frac{168}{1000}$ [1000 in the denominator, so point will be three numbers from right end]
$\frac{168}{1000} = 0.168$
Therefore the expression $1.4 \times 0.12$ in decimal is $0.168$
