Respuesta :
if you multiply decimals , the estimate value is necessary ! it could be understood easily, if at any place the number exceeds 4 , then the value in front is raised by one !as;2.234 = 2.23 , it will remain same but,2.235 = 2.24 the 3 raised to 5
Step-by-step explanation:
The product of two decimal numbers 5.4 and 3.7 would be,
estimated answer = 20
actual answer = 19.98
What is decimal number?
"A number whose whole number part and the fractional part is separated by a decimal point."
What is estimation of decimal?
"To find a estimate using decimal numbers, round the decimal to the nearest whole number."
For given question,
Consider two decimal numbers 5.4 and 3.7
We need to find the product of above decimal numbers.
First we estimate the first decimal number.
We know that if the number at the tenth place is less than 5, round the number down to the nearest whole number.
So, 5.4 ≈ 5
Now, we estimate the second decimal number.
We know that if the number at the tenth place is greater than or equal to 5, round the number down to the nearest whole number.
So, 3.7 ≈ 4
Now we find the product of above decimal numbers.
The actual answer would be,
5.4 × 3.7 = 19.98
The product of estimated decimal numbers would be,
5 × 4 = 20
We can observe that both the answers are approximately equal.
Therefore, the product of two decimal numbers 5.4 and 3.7 would be,
estimated answer = 20
actual answer = 19.98
