Evaluate : ii) 3.2× 2.5× 0.7
Given: 3.2 × 2.5 × 0.7
We know that decimals are one of the types of numbers. The decimal number contains two parts such as the whole number part and the fractional part, which are separated by the decimal point. The number which is appearing before the decimal point is called the whole number part and the numbers appearing after the decimal point is called the fractional part. The decimal number can be classified into different types such as recurring decimal numbers and non-recurring decimal numbers.
To multiply the decimal numbers 3.2 × 2.5 × 0.7, follow the below steps:
Remove the decimals for now and multiply the numbers,
32 × 25 × 7 = 5600
This implies that the product of 32, 25 and 7 is 5600.
Now, count the number of decimal places from each decimal number.
So, 3.2 has 1 decimal place, 2.5 has 1 decimal place and 0.7 has 1 decimal place.
So, their product will have 1+1+1=3 decimal places.
Therefore, 3.2 × 2.5 × 0.7 = 5.6
Hence, the product of 3.2, 2.5 and 0.7 is 5.6.
