Rounding Numbers Practice

Introduction to rounding numbers practice:

In this article we discuss to find the rounding numbers practice solving problems. The rounding numbers or digits are only approximate. An exact solutions are generally cannot be obtain using rounding numbers or digits. If the number 0, 1, 2, 3, 4, do not change the rounding numbers. All the numbers are right side of the requested rounding number will become 0.The number 5, 6, 7, 8, 9 rounding number round up by one number. Let us see to rounding numbers practice solving problems are given below.I like to share this Rounding Decimals with you all through my article.

Rounding Numbers Practice-example Problems:

Example 1:

Round off 3247 to the nearest ten.

Solution:

We note that 3247 lies between 3240 and 3250

3247 is closer to 3250 than to 3240

(Since 3250 – 3247 = 3, while 3247 – 3240 = 7)

Hence, 3247 when rounded off to the nearest ten becomes 3250.

Example 2:

Round off 3247 to the nearest hundred

Solution:

We further note that 3247 lies between 3200 and 3300

3247 is closer to 3200 than to 3300

(Since 3300 – 3247 = 53, while 3247 – 3200 = 47)

Hence, 3247 when rounded off to the nearest hundred becomes 3200.

Example 3:

Round off 3247 to the nearest thousand

Solution:

Finally, we note that 3247 lies between 3000 and 4000

3247 is closer to 3000 than to 4000

(Since 3247 – 3000 = 245, while 4000 – 3247 = 755)

Hence, 3247 when rounded off to the nearest thousand becomes 3000.

Example 4:

Round off 5257 to the nearest thousand

Solution:

Finally, we note that 5257 lies between 5000 and 6000

5257 is closer to 5000 than to 6000

(Since 5257 – 5000 = 257, while 6000 – 5257 = 743)

Hence, 5257 when rounded off to the nearest thousand becomes 5000.I have recently faced lot of problem while learning translation in math, But thank to online resources of math which helped me to learn myself easily on net.
