120/60 = 2, 300/60 = 5, 120/300 = 2/5
5
313
It is: 3.45*10^5
1/5 of 300 = 60
You write 325 in standard form as 3.25 × 102
60
It is 5/300 or 1/60 in its simplest form
Add them up: 5 + 300 + 8 = 513 I suspect that you may have a zero missing: either: 50 + 300 + 8 = 358 or: 5 + 300 + 80 = 385 Expanded form is usually written with the biggest number first and the rest in decreasing value, ie 358 = 300 + 50 + 8 385 = 300 + 80 + 5
365.24 = 300 + 60 + 5 + 0.2 + 0.04
65.09
300,000 in standard form is written as 3 x 10^5. This is because standard form is a way of writing numbers by using powers of 10. In this case, 3 is the coefficient and 5 is the exponent, indicating that the decimal point has been moved 5 places to the right to create the number 300,000.
