The easiest way to go from fraction to decimal is to put the value over 10 ^ n where n = any positive integer. This means that for 3/4, multiply by 25/25 to get 75/100. 75/100 is obviously .75 because .xy is xy/100. To go from 1.44 to fraction, do the same in reverse. 1.44 = 144/100. 144/100 is equal to 36/25. Because the prime factors of 36 are 2 ^ 2, and 3 ^ 2, and the prime factors of 25 are 5 ^ 2, there are no common factors and the number cannot be simplified further.
To Turn Fraction into Decimal, Do the top number divided by bottom number (;p, Forgot what they called); in this case 3 divided by 4. to turn Decimal into fraction, just put 100 under number and times the number by 100.
A fraction consists of 2 integers, so be a good boy and get them: 1.44 = 144 / 100. Omg wow we have a fraction. If the decimals are repeating it's still a rational number can be expressed with a fraction: Wiki.
