Question

在数 $74982.1035$ 中，数字 $9$ 所在位的位值是数字 $3$ 所在位的位值的多少倍？

In the number $74982.1035$ the value of the place occupied by the digit $9$ is how many times as great as the value of the place occupied by the digit $3?$

$1{,}000$

$10{,}000$

$100{,}000$

$1{,}000{,}000$

$10{,}000{,}000$

答案：C

知识点：位值指数

难度评级：820

小提示：

位值每向左移动一位就乘以 $10$

Each step left in place value multiplies by $10$

大提示：

比较 $9$ 和 $3$ 所在位置的位值

Compare the place values occupied by $9$ and $3$

解答：

每个数字所在位的位值都是它右边一位的十倍。

数字 $9$ 所在位比数字 $3$ 所在位向左 $5$ 位。

因此它的位值是 $10^5 = 100,000$ 倍。

所以正确答案是 C。

Note that each digit has ten times the value of the digit to its right.

The place occupied by $9$ is $5$ spaces to the left of the place occupied by $3.$

This means that it is $10^5 = 100,000$ times as great.

Thus, C is the correct answer.
