## Math in Focus Grade 5 Chapter 1 Practice 1 Answer Key Numbers to 10,000,000

Count on or back by ten thousand or hundred thousand. Then fill in the blanks.

Question 1.
40,000 50,000 60,000 _____ ____
Place value in Maths describes the position or place of a digit in a number. Each digit has a place in a number. When we represent the number in the general form,  the position of each digit will be expanded. Those positions start from a unit place or we also call it one’s position. The order of place value of digits of a number of right to left is units, tens, hundreds, thousands, ten thousand, a hundred thousand, and so on.
The number 40,000:

The ten thousand place value for 40,000 is 4.
The number 50,000:

The ten thousand place value for 50,000 is 5.
The number 60,000:

The ten thousand place value for 60,000 is 6.
