15a+11b8\frac{15a+11b}{8}

Here are the solutions to the problems:

1. Simplify 3a+5b4+9a+b8\frac{3a+5b}{4} + \frac{9a+b}{8}

Step 1: Find a common denominator for 4 and 8, which is 8. 3a+5b4+9a+b8=2(3a+5b)24+9a+b8\frac{3a+5b}{4} + \frac{9a+b}{8} = \frac{2(3a+5b)}{2 \cdot 4} + \frac{9a+b}{8}

Step 2: Rewrite the first fraction with the common denominator. =6a+10b8+9a+b8= \frac{6a+10b}{8} + \frac{9a+b}{8}

Step 3: Add the numerators and combine like terms. =6a+10b+9a+b8=(6a+9a)+(10b+b)8= \frac{6a+10b+9a+b}{8} = \frac{(6a+9a)+(10b+b)}{8} =15a+11b8= \frac{15a+11b}{8} The simplified expression is 15a+11b8\boxed{\frac{15a+11b}{8}}.

2. Simplify 2x6+2x3y3+x+y2\frac{2x}{6} + \frac{2x-3y}{3} + \frac{x+y}{2}

Step 1: Find a common denominator for 6, 3, and 2, which is 6. 2x6+2x3y3+x+y2=2x6+2(2x3y)23+3(x+y)32\frac{2x}{6} + \frac{2x-3y}{3} + \frac{x+y}{2} = \frac{2x}{6} + \frac{2(2x-3y)}{2 \cdot 3} + \frac{3(x+y)}{3 \cdot 2}

Step 2: Rewrite each fraction with the common denominator. =2x6+4x6y6+3x+3y6= \frac{2x}{6} + \frac{4x-6y}{6} + \frac{3x+3y}{6}

Step 3: Add the numerators and combine like terms. =2x+4x6y+3x+3y6=(2x+4x+3x)+(6y+3y)6= \frac{2x+4x-6y+3x+3y}{6} = \frac{(2x+4x+3x)+(-6y+3y)}{6} =9x3y6= \frac{9x-3y}{6}

Step 4: Factor out the common term in the numerator and simplify the fraction. =3(3xy)6=3xy2= \frac{3(3x-y)}{6} = \frac{3x-y}{2} The simplified expression is 3xy2\boxed{\frac{3x-y}{2}}.

3. Simplify 2a+4b43(a4b)6\frac{2a+4b}{4} - \frac{3(a-4b)}{6}

Step 1: Simplify each fraction individually. 2a+4b4=2(a+2b)4=a+2b2\frac{2a+4b}{4} = \frac{2(a+2b)}{4} = \frac{a+2b}{2} 3(a4b)6=a4b2\frac{3(a-4b)}{6} = \frac{a-4b}{2}

Step 2: Substitute the simplified fractions back into the expression. a+2b2a4b2\frac{a+2b}{2} - \frac{a-4b}{2}

Step 3: Subtract the numerators since they have a common denominator. =(a+2b)(a4b)2=a+2ba+4b2= \frac{(a+2b)-(a-4b)}{2} = \frac{a+2b-a+4b}{2}

Step 4: Combine like terms. =(aa)+(2b+4b)2=6b2= \frac{(a-a)+(2b+4b)}{2} = \frac{6b}{2}

Step 5: Simplify the fraction. =3b= 3b The simplified expression is 3b\boxed{3b}.

4. Simplify 3e+e24+e3\frac{3e+e^2}{4} + \frac{e}{3} (Assuming the operation between the two fractions is addition, as it is a common convention when an operator is missing in such problems.)

Step 1: Find a common denominator for 4 and 3, which is 12. 3e+e24+e3=3(3e+e2)34+4e43\frac{3e+e^2}{4} + \frac{e}{3} = \frac{3(3e+e^2)}{3 \cdot 4} + \frac{4e}{4 \cdot 3}

Step 2: Rewrite each fraction with the common denominator. =9e+3e212+4e12= \frac{9e+3e^2}{12} + \frac{4e}{12}

Step 3: Add the numerators and combine like terms. =9e+3e2+4e12=3e2+(9e+4e)12= \frac{9e+3e^2+4e}{12} = \frac{3e^2+(9e+4e)}{12} =3e2+13e12= \frac{3e^2+13e}{12} The simplified expression is 3e2+13e12\boxed{\frac{3e^2+13e}{12}}.

5. Simplify 55+482524\frac{5 \cdot 5+4}{8} - \frac{25-2}{4}

Step 1: Calculate the numerators. 55+4=25+4=295 \cdot 5+4 = 25+4 = 29 252=2325-2 = 23

Step 2: Substitute the calculated numerators back into the expression. 298234\frac{29}{8} - \frac{23}{4}

Step 3: Find a common denominator for 8 and 4, which is 8. =29822324= \frac{29}{8} - \frac{2 \cdot 23}{2 \cdot 4}

Step 4: Rewrite the second fraction with the common denominator. =298468= \frac{29}{8} - \frac{46}{8}

Step 5: Subtract the numerators. =29468=178= \frac{29-46}{8} = \frac{-17}{8} The simplified expression is 178\boxed{-\frac{17}{8}}.

Here are the solutions to the problems: 1. Simplify (3a+5b)/(4) + (9a+b)/(8) Step 1: Find a common denominator for 4 and 8, which is 8. (3a+5b)/(4) + (9a+b)/(8) = (2(3a+5b))/(2 · 4) + (9a+b)/(8) Step 2: Rewrite the first fraction with the common denominator. = (6a+10b)/(8) + (9a+b)/(8) Step 3: Add the numerators and combine like terms. = (6a+10b+9a+b)/(8) = ((6a+9a)+(10b+b))/(8) = (15a+11b)/(8) The simplified expression is (15a+11b)/(8). 2. Simplify (2x)/(6) + (2x-3y)/(3) + (x+y)/(2) Step 1: Find a common denominator for 6, 3, and 2, which is 6. (2x)/(6) + (2x-3y)/(3) + (x+y)/(2) = (2x)/(6) + (2(2x-3y))/(2 · 3) + (3(x+y))/(3 · 2) Step 2: Rewrite each fraction with the common denominator. = (2x)/(6) + (4x-6y)/(6) + (3x+3y)/(6) Step 3: Add the numerators and combine like terms. = (2x+4x-6y+3x+3y)/(6) = ((2x+4x+3x)+(-6y+3y))/(6) = (9x-3y)/(6) Step 4: Factor out the common term in the numerator and simplify the fraction. = (3(3x-y))/(6) = (3x-y)/(2) The simplified expression is (3x-y)/(2). 3. Simplify (2a+4b)/(4) - (3(a-4b))/(6) Step 1: Simplify each fraction individually. (2a+4b)/(4) = (2(a+2b))/(4) = (a+2b)/(2) (3(a-4b))/(6) = (a-4b)/(2) Step 2: Substitute the simplified fractions back into the expression. (a+2b)/(2) - (a-4b)/(2) Step 3: Subtract the numerators since they have a common denominator. = ((a+2b)-(a-4b))/(2) = (a+2b-a+4b)/(2) Step 4: Combine like terms. = ((a-a)+(2b+4b))/(2) = (6b)/(2) Step 5: Simplify the fraction. = 3b The simplified expression is 3b. 4.
