Nearest thousand-

Round the numbers to the nearest thousand.

To round the numbers to the nearest thousand we need to look at the last three digits. If the last three digits are 500 or more than the 500 then round the thousand digit up.If the last three digits are less than the 500 then round down by keeping the thousand digit same.

Given numbers are,

11) 345,246-

As the last three digits are less than 500 thus round down by keeping the thousand digit same.

Thus the round of above number to the nearest thousand is 345000.

12) 127825-

As the last three digits are more than 500 thus round the thousand digit up.

Thus the round of above number to the nearest thousand is 128000.

Nearest tenth

Round the following numbers to the nearest tenth.

To round the numbers to the nearest tenth we need to look at the last digit. If the last digit is 5 or more than the 5 then round the tenth digit up.If the last digit is less than the 5 then round down by keeping the tenth digit same.

Given numbers are,

13) 42.51-

As the last three digits are less than 5 thus round down by keeping the thousand digit same.

Thus the round of above number to the nearest tenth is 42.

14) 39.62-

As the last digit is more than 5 thus round the tenth digit up.

Thus the round of above number to the nearest tenth is 40.

Nearest cent and dollar

Round the numbers to the nearest cent and dollar.

To round the numbers to the nearest cent we need to look at the last two digits after the decimal point. If the last two digits after the decimal points are 50 or more than the 50 then round the cent digit up.If the last two digits after the decimal point are less than the 50 then round down by keeping the cent digit same.

To round the numbers to the nearest dollar we need to look at the last digit after the decimal. If the last digit after the decimal is 5 or more than the 5 then round the dollar digit up.If the last digit after the decimal is less than the 5 then round down by keeping the dollar digit same.

Given numbers are,

15)$365.473-

As the last two digits after the decimal are less than 50 thus round down by keeping the cent digit same.

Thus the round of above number to the cent is $365.47.

As the last digit after the decimal point is less than 5 thus round down by keeping the dollar digit same.

Thus the round of above number to the nearest dollar is $365.

16) $125.654-

As the last two digits after the decimal point are more than 50 thus round the cent digit up.

Thus the round of above number to the nearest cent is $125.66.

As the last digit after the decimal point is more than 5 thus round the dollar digit up.

Thus the round of above number to the nearest dollar is $126.

Hence,

Round the numbers to the nearest thousand.

11) 345,000
