Question

Which is true of the number 55,555?

A.Each digit has a value less than the value of the digit to its right and greater than the value of the digit to its left.
B.Each digit has a value 10 times the value of the digit to its right and 10 times the value of the digit to its left.
C.Each digit has a value 110 of the value of the digit to its right and 10 times the value of the digit to its left.
D.Each digit has a value 10 times the value of the digit to its right and 110 of the value of the digit to its left.

Answer 1

Answer:

  D.  Each digit has a value 10 times the value of the digit to its right and 1/10 of the value of the digit to its left

Step-by-step explanation:

Digits increase in value by a factor of 10 for each place you move to the left. Hence a digit to the right has 1/10 the value.

Comment on place value

The multiplier for a base-10 (decimal) number system is 10 as you move one place to the left. In some other base, the multiplier is that base. In a binary (base-2) number system, each "bit" increases in value by a factor of 2 as you move to the left.

Answer 2

• The number would be a math object used in counting, measurement, and labeling.
• The numbers are increased by 10 for every spot to the left.
• Therefore, $\bold{\frac{1}{10}}$ is the value in a right digit.
• When you move one place to the left, there is a multiplier for a 10-base system (decimal number).
• The multiplier is this base in some other base.
• In each "bit" boosts a value by a factor of 2 in a binary (base-2) number system when one moves left.

Therefore, the "Choice D" is the only correct answer.
