It is already in standard form as written.
It is: 1.56*10^-5 in standard form or scientific notation
6 and 240/1000 = 6 and 24/100 = 6 and 6/25 or 156/25 or 6.24 in decimal
Writing a number in standard form simply means to express the number in its 'normal' form. Therefore, your example is written in standard form as: 156
156 times 10^7 is 1.56*10^9 in standard form or scientific notation
It is already in standard form as written.
156/200 = 0.78
It is: 1.56*10^-5 in standard form or scientific notation
0.156 is already a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. Its equivalent, in rational form, is 156/1000. You can simplify that if you so wish.
what is this fraction in simplest form 75/156
156.0
0.2308
20/156=5/39
6 and 240/1000 = 6 and 24/100 = 6 and 6/25 or 156/25 or 6.24 in decimal
It is quite simple to change a decimal form into a fraction. Any number , including a decimal can be divided by 1, and multiplied by 1. Take the decimal .156 for example first divide it by 1; yields .156/1 now do some fraction multiplication (.156/1) x (1000/1000) (note 1000/1000 =1, so mult of the decimal dosen't change its value) this yields 156/1000 , so .156 = 156 thousandths ------------------------------------------------------------------ A more interesting problem arises from trying to expand a repeating decimal example .175175175175175............and so on Let X =.175175175175175.......... then 1000X=175.175175175......... (note the decimal place after 175) so 1000X-1X=999X = 175 then dividing by 999 gives x=175/999 so .175175175.........=175/999 as a fraction.
