Question

A number is 42,300 when multiplied by 10 . Find the product of this number and 500.

Answer 1

The answer is 2,115,000.

First, you want to find the number itself. Think of the number as "x." So, "x" times 10 = 42,300. To figure this out, you want "x" by itself on one side of the equal sign. To do so, you divide 42,300 by 10: 4,230. Next, to find the product of 4,230 and 500, you multiply them together: 4,230 times 500 = 2,115,000.

Answer 2

2,115,000

Further explanation

We will solve the problem of multiplication operations.

Given:

A number is 42,300 when multiplied by 10.

Question:

Find the product of this number and 500.

The Process:

Let the number as N.

N multiplied by 10 equals 42,300.

$\boxed{ \ N+N+N+N+N+N+N+N+N+N = 42,300 \ }$

$\boxed{ \ 10 \times N = 42,300 \ }$

• Because 42,300 contains two zeros while 10 has one zero, thus N has one zero.
• $\boxed{ \ 423 \times 1 = 423 \ }$

Based on the two reasons above, we can conclude that the value of N is 4.230. So, the number in question is $\boxed{ \ 4,230 \ }$.

Another way to get N is to divide 42,300 by 10.

$\boxed{ \ N = 42,300 \div 10 \rightarrow \boxed{ \ N = 4,230 \ } \ }$

Now we proceed to find the product of this number and 500.

$\boxed{ \ 4,230 \times 500 = ? \ }$

$\boxed{ \ 423 \times 5 \times 1,000 = ? \ }$

$\boxed{ \ 2,115 \times 1,000 = 2,115,000 \ }$

Thus, the product of this number and 500 is $\boxed{\boxed{ \ 2,115,000 \ }}$.
