9/4w=13/14+2

1 answer

To solve the equation \( \frac{9}{4}w = \frac{13}{14} + 2 \), we first need to simplify the right side of the equation.

Start by converting the whole number 2 to a fraction with a common denominator of 14:

\[ 2 = \frac{2 \times 14}{1 \times 14} = \frac{28}{14} \]

Now, we can combine the fractions on the right side:

\[ \frac{13}{14} + \frac{28}{14} = \frac{13 + 28}{14} = \frac{41}{14} \]

Now the equation is:

\[ \frac{9}{4}w = \frac{41}{14} \]

Next, we want to isolate \( w \). We can do this by multiplying both sides by the reciprocal of \( \frac{9}{4} \), which is \( \frac{4}{9} \):

\[ w = \frac{41}{14} \cdot \frac{4}{9} \]

Now we multiply the fractions:

\[ w = \frac{41 \cdot 4}{14 \cdot 9} = \frac{164}{126} \]

Next, we simplify \( \frac{164}{126} \) by finding the greatest common divisor (GCD) of 164 and 126. The GCD is 2, so we divide both the numerator and the denominator by 2:

\[ w = \frac{164 \div 2}{126 \div 2} = \frac{82}{63} \]

Thus, the solution for \( w \) is:

\[ \boxed{\frac{82}{63}} \]
