How do the values of the 5s in 581.03 and 5.472 compare
Nonamiya [84]

The value of the 5 in 581.03 is 100 times the value of the 5 in 5.472

Step-by-step explanation:

Each digit in a number has a place value.

The place value of 4 in 453.56 is hundreds (100), because 4 is in the hundred place

The place value of 2 in 1782.56 is ones (1), because 2 is in the unit place

The place value of 3 in 2.345 is tenth (0.1), because 3 is in the tenth place

∵ The number is 581.03

- Find the place of 5 in the number

∵ 5 is in the hundred place

∴ The place value of 5 is 100

∵ The number is 5.472

- Find the place of 5 in the number

∵ 5 is in the unit place

∴ The place value of 5 is 1

To find the value of the 5 in 581.03 is how many times the value of the 5 in 5.472 divide the place values of them

∵ 100 ÷ 1 = 100

∴ The value of 5 in 581.03 = 100 times the value of 5 in 5.472

The value of the 5 in 581.03 is 100 times the value of the 5 in 5.472
