It is: 204/306 = 2/3 simplified
3.06 *10^11
Writing a number in standard form simply means to express the number in its 'normal' form. Therefore, the way you wrote the number is the standard form for your example.
Three hundred six million, three hundred twenty
306*15 = 4590
It is: 204/306 = 2/3 simplified
252=2x2x3x3x7. 306=2x3x3x17. They both share 2x3x3=18. Divide both numbers by 18. Now, in simplest form, 252/306=14/17.
306 ÷ 272 = 1 34/272 = 1 1/8 = 1.125
