Final answer:
This question pertains to the process of expanding a number from standard form into its expanded form, which breaks down the number based on the value of each digit according to its position. The example provided was the number 57.9, which expands to 5 × 10 + 7 × 1 + 9 × 0.1.
Step-by-step explanation:
This question is about the comparison and conversion between Standard form and Expanded form in mathematics. Each digit in a number has a place value, meaning it represents a certain amount depending on its position in the number.
For example, the number 57.9 in standard form can be expanded as: 5 × 10 + 7 × 1 + 9 × 0.1. The first digit 5 is in the tens place, so it is multiplied by 10. The next digit 7 is in the ones place, so it is multiplied by 1. The number after the decimal point, 9, is in the tenths place, so it is multiplied by 0.1.
The provided numbers 5.079 and 0.579 seem to be incorrectly linked to the given expanded form. I believe there may have been a mix-up in the question details.
