The numerater of a fraction is 3 less than the denomintater If the numerater is increased by 6 and denominter by 5 The fraction is doubled in value find original fraction?
Sherry987
2(x/(x + 3)) = (x + 6)/(x + 8)
ie 2x/(x + 3)= (x + 6)/(x + 8)
Cross multiply: 2x(x + 8)= (x + 3)(x + 6)
ie 2x2 + 16x = x2 + 9x + 18
ie x2 + 7x - 18 = 0
Factorise: (x + 9)(x - 2) = 0
ie x = 2, fraction = 2/5
Check: 2/5 x 2 = 8/10? Yes. Job done
(x could also be -9, fraction -9/-6 which is half of -3/-1)

The original fraction is -145/(-282) or it could be 850/35700 or one of infinitely many possibilities.
Why do you have to multiply or divide both the numerater and denominator of a fraction to find an equivalent fraction?
Whatever you multiply or divide the numerator by, you must do the same to the denominator. If you multiply or divide the numerator and denominator by different numbers, you change the value of the fraction and turn it into a different number. After that, nothing is "equivalent" any more ... you're working with a changed number.
What is the rule to change a mixed number to improper fraction?
first you multiply the whole number by the denominator then add the numerater to the product then put the answer over the denominator e.g. 5 4/7 5x7=35 35+4=39 39 over 7 TADA!!
What do you call a fraction in which the numerater is greater than the denominator?

You flip the denominator on top of the fraction. So the fraction would be upside-down par say. The first number stays the same, the second you would flip. Simpler terms: the numerater goes inside the box
