Expanded Form (A) Homework

The number 555 can be expanded as 500+50+5. This is because the first digit, 5, represents 500, the second digit, 5, represents 50, and the third digit, 5, represents 5. Therefore, when we add these three values together, we get the expanded form of 555 as 500+50+5.

The given number, 644, can be expanded into 600+40+4.

The given number, 528, can be written in expanded form as 500+20+8. In expanded form, each digit is written separately based on its place value, and then all the terms are added together. In this case, the digit 5 represents 500, the digit 2 represents 20, and the digit 8 represents 8. Adding these terms together gives us the original number, 528.

The given expression is 200+90+7. To write this number in standard form, we simply add the digits together, which gives us 297.

The given expression is 400+80+9, which can be simplified by adding the numbers together. When we add 400, 80, and 9, we get the sum of 489. Therefore, the number in standard form is 489.

The given expression is 800+40+1. When we add these numbers together, we get 841. Therefore, the number in standard form is 841.

The given expression is 200+70+8. When we add these numbers, we get the sum of 278.

The given question asks to write the number in standard form. The standard form of a number is the usual way of writing a number, with digits arranged in descending order of magnitude. In this case, the number is already in standard form, as it is written with the hundreds digit first, followed by the tens digit, and then the units digit. Therefore, the answer is 554.

The number 707 can be written in expanded form as 700+0+7, 700+7, or 700+00+7. In expanded form, each digit is written as a separate term, with its place value included.

The given number, 964, can be expressed in expanded form as 900+60+4. In expanded form, each digit is written as a sum of its place value. The digit 9 is in the hundreds place, so it is multiplied by 100 (900). The digit 6 is in the tens place, so it is multiplied by 10 (60). The digit 4 is in the ones place, so it is written as is (4). Adding these three terms together gives the expanded form of the number.

The given question asks to write the number 200+70 in standard form. In standard form, we write numbers using digits and place value. Adding 200 and 70 gives us a sum of 270. Therefore, the correct answer is 270.
