What is the expression 7b-3(b-1) in simplest form?
I could, if I knew what was to be expressed in such a manner.
To convert a decimal to a fraction, take a look at how many places the decimal takes up (this does not include zeros). There is only one, the tens place. So place 3 over 10. S…ince it is already in simplest form, that is your answer(3/10).
Make the decimal a fraction, which is usually one or two digits over 100. Decimal percentages will be expressed using larger denominators. One way of saying this is to write… the numbers after the decimal, over 1 followed by as many 0's as there are numbers after the decimal. Examples: .5 = 5/10 .28 = 28/100 .402 = 402/1000 .5525 = 5525/10000 Reduce the fraction to its simplest form by dividing the numerator and denominator by the same number, which is the same as dividing by 1. Example: 28/100 divided by 4/4 = 7/25 -- this is the simplest form 402/1000 divided by 2/2 = 201/500 -- this is simplest form (201 = 67x3) 5525/10000 divided by 25/25 = 221/400 -- this is simplest form (221 = 13x17) the numbers after the decimal over 1 followed by as many 0's as there are numbers after the decimal. 1) You convert the decimal to a fraction. 2) You simplify the fraction in the usual way. For step 1, count the number of decimal digits. Use a "1", followed by that many zeros, in the denominator. Write the decimal number WITHOUT a decimal point in the numerator. Here is an example: Convert 3.225 to a fraction. Three decimal digits; so the denominator is 1000 (three zeros); your fraction is 3225 / 1000. For step 2, the prime factors of the denominator can only be 2 and 5; for example, you don't need to check whether both numbers are multiples of 3, or of 7 - they won't.
(7 x 7) - (5 x 3)
8/20 = 4/10 = 2/5
When you have done all the multiplication and added all the like term possible.
3 2/3 - 5/12
2.045 = 409/200
When the numerator and denominator are coprime - ie have no factor in common other than 1.
if you have 3 out of 9 you have to divide first by the GCF which is 3 and after you divide you will get 1 out of 3 and that's your answer!
