Evaluate:v 1.2× 1.2× 0.4
Given: 1.2 × 1.2 × 0.4
In Mathematics, the decimal number is a kind of number, whose whole number part and the fractional part are separated by a decimal point. The number that lies before the decimal point is considered to be the whole number part and the number that lies after the decimal point is considered to be the fractional part.
Let us take an example, 1.2. We know that 1.2 is a decimal number.
Here, 1 is in the whole number part and 2 is in the tenth’s place, and it can be written as 2/10. Hence, 2/10 is the fractional part.
To multiply 1.2 × 1.2 × 0.4, first, ignore the decimal point.
Hene, 12 × 12 × 4 = 576.
Now, from the given expression, count the number of decimal places.
Hence, 1.2 has 1 decimal place and is multiplied twice, and 0.4 has 1 decimal place.
Therefore, their product will have 3 decimal places.
Therefore, 1.2 × 1.2 × 0.4 = 0. 576
Therefore, the product of 1.2, 1.2 and 0.4 is 0.576.
