Answer to Problem 1P

The whole number 250,374 is written as “Two hundred fifty thousands, three hundred seventy four”.

Explanation of Solution

The whole number is 250,374                                                                              .

The count of digit places in the number is 6.

4 stands at ones place, 7 stands at tens place, 3 stands at hundreds place, 0 stands in thousands place, 5 stands in ten thousands place and 2 stands in hundred thousands place.

The digits before comma can be written as “Two hundred fifty” and digits after comma can be written as “Three hundred seventy four”.

However, the digits before comma are in thousands range; hence is written as “Two hundred fifty thousands”.

On joining, the number becomes “Two hundred fifty thousands, three hundred seventy four”.

Therefore, the whole number 250,374 is written as “Two hundred fifty thousands, three hundred seventy four”.

Answer to Problem 1P

The words “One million, sixty-five thousand, eight” in numerical form is 1,065,008.

Explanation of Solution

The words are “One million, sixty-five thousand, eight”.

The count of digit places in the number must be 7.

The words are separated by commas that make 3 parts: first part includes the words, “one million”, second part includes “sixty-five thousand” and the third part includes just, “eight”.

“One million” in numerical form becomes $1,000,000$.

“Sixty-five thousand” in numerical form becomes 65,000.

“Eight” in numerical form is 8.

Add the numbers obtained.

$1,000,000+65,000+8=1,065,008$

Therefore, the words “One million, sixty-five thousand, eight” in numerical form is 1,065,008.
