Question 11. Estimate the product of 275 & 135 by rounding off to the nearest hundred.
Answers
Answer:
Step-by-step explanation:
275 nearest hundred. - 300
135 nearest hundred. - 100
Given: The numbers 275 and 135.
To Find: The estimated product of 275 and 135 by rounding off to the nearest hundred.
Solution:
To estimate the product of two numbers, the multiplier and multiplicand need to be rounded off to nearest hundred.
In 275, the last two digits is 75 and it is greater than 50.
Hence, to round off the value 275, 1 will be added to the hundreds place value and remaining place values will become zero.
After rounding off to the nearest hundred, the value of 275 will be 300.
In 135, the last two digit is 35 and it is less than 50.
Thus, to round off the value 135, the hundreds place value will remain same and the remaining place value will become zero.
After rounding off to nearest hundred, the value of 135 will be 100.
The product of two rounded off values 300 and 100 is,
300×100=30000
Therefore, the estimated product of 275 and 135 by rounding off to the nearest hundred is 30000.
