Question

Find the product of the place values 2 in 4, 28, 721​

Answer 1

To find place value of digits:

• For ones place, multiply by 1
• For tens place, multiply by 10
• For hundreds place, multiply by 100
• For thousands place, multiply by 1000
• Next are 10000, 100000, ... .

Now we solve the given problem:

The given number is 428721

In this number, there are 2 in two places -

• in tens place; place value = 2 × 10 = 20
• in ten thousands place; place value = 2 × 10000 = 20000

Therefore the product of the place values of 2 is

= 20 * 20000

= 400000
