Studdy Solution

STEP 1

1. The given expression represents a proportion, where 1:4(1/2)1: 4(1 / 2) is equivalent to x:2(3/4)x: 2(3 / 4).
2. To solve for xx, we can set up a ratio and solve the resulting equation.
3. The numbers involved are mixed numbers and can be converted to improper fractions for ease of calculation.

STEP 2

1. Convert mixed numbers to improper fractions.
2. Set up the proportion as an equation.
3. Solve the equation for xx.
4. Convert the solution back to a mixed number if necessary.

STEP 3

Convert the mixed number 4(1/2)4(1 / 2) to an improper fraction.
4(1/2)=4+12=82+12=92 4(1 / 2) = 4 + \frac{1}{2} = \frac{8}{2} + \frac{1}{2} = \frac{9}{2}

STEP 4

Convert the mixed number 2(3/4)2(3 / 4) to an improper fraction.
2(3/4)=2+34=84+34=114 2(3 / 4) = 2 + \frac{3}{4} = \frac{8}{4} + \frac{3}{4} = \frac{11}{4}

STEP 5

Set up the proportion as an equation using the improper fractions.
192=x114 \frac{1}{\frac{9}{2}} = \frac{x}{\frac{11}{4}}

STEP 6

Cross-multiply to solve for xx.
1114=x92 1 \cdot \frac{11}{4} = x \cdot \frac{9}{2}

STEP 7

Simplify the equation to isolate xx.
114=92x \frac{11}{4} = \frac{9}{2}x

STEP 8

Multiply both sides of the equation by the reciprocal of 92\frac{9}{2} to solve for xx.
x=11429 x = \frac{11}{4} \cdot \frac{2}{9}

STEP 9

Simplify the right side of the equation to find the value of xx.
x=11249 x = \frac{11 \cdot 2}{4 \cdot 9}

STEP 10

Further simplify the fraction by multiplying the numerators and denominators.
x=2236 x = \frac{22}{36}

STEP 11

Reduce the fraction to its simplest form.
x=22÷236÷2=1118 x = \frac{22 \div 2}{36 \div 2} = \frac{11}{18}

STEP 12

Since the solution is already in simplest form and does not require conversion back to a mixed number, we can state the final solution.
x=1118 x = \frac{11}{18}
