253 million = 253,000,000
Remember the digits names.
0 = units
00 = tens
000 = hundreds
0,000 = thousands
00,000 = tens of thousands
000,000 - hundreds of thousands
0,000,000= millions.
00,000,000 = tens of millions
000,000,000 = hundreds of millions ( as the given number).
So you need 'seven; digits in a number to reach a million. The commas are used to separate every three digits. A full stop / period is only used to indicate decimals.
It is a whole number and its simplest form is 253.
2.53 X 102 ======= Sometime writing scientific notation is extraneous work. 253 is short enough to write in standard form, usually.
253
You write 8.8 million as 8,800,000
10 13/24 To explain this answer: 24 can go into 253 a total of 10 times. That creates the 10. 24 * 10 = 240. The difference between 253 and 240 (253 - 240) is 13. That gets the 13. Denominator stays the same. That gets the 24.
Write 453 in standard form
It is a whole number and its simplest form is 253.
2.53 X 102 ======= Sometime writing scientific notation is extraneous work. 253 is short enough to write in standard form, usually.
253/25 written as a mixed number is 10 and 3/25
2.53 = 253/100
It is: 5.06 = 253/50
253
253
2.024 = 2024/1000 = (253×8)/(125×8) = 253/125 (as an improper fraction) = 2 3/125 (as a mixed number)
Write 1.98 million is 1,980,000
You write 8.8 million as 8,800,000
youranswer would be -23x+y=-253 because you add 23x to both sides (to y and itself)
