You first have to start by drawing a number line and mark two integers between the fraction lines. Then you have to divide the section between the two integers in an equal number of parts which is equal to the denominator.
G = x Felicia is Gabriella's age + 6 F = x + 6 Their mother is twice Felicia's age M = 2(x + 6) or 2x + 12 Tanya is the age of their mother plus Gabriella's age A = 2x + 12 + x = 3x + 12 3x + 12
800-20 is 780. A third of 780 is 780(1/3) = 260. 780 - 260 = 520. 25% of $520 is 0.25(520) = 130. 520 - 130 = 390. One sixth of 390 is 390(1/6) = 65. 390 - 65 = 325. So, Bob kept $325 for himself.
