Solve for v v+3/4=1/8

$v + \frac{3}{4} = \frac{1}{8}$

Step 1

Subtract $\frac{3}{4}$ from both sides of the equation.

$v = \frac{1}{8} - \frac{3}{4}$

Step 2

To write $- \frac{3}{4}$ as a fraction with a common denominator, multiply by $\frac{2}{2}$ .

$v = \frac{1}{8} - \frac{3}{4} \cdot \frac{2}{2}$

Step 3

Write each expression with a common denominator of $8$ , by multiplying each by an appropriate factor of $1$ .

Multiply $\frac{3}{4}$ by $\frac{2}{2}$ .

$v = \frac{1}{8} - \frac{3 \cdot 2}{4 \cdot 2}$

Multiply $4$ by $2$ .

$v = \frac{1}{8} - \frac{3 \cdot 2}{8}$

Step 4

Combine the numerators over the common denominator.

$v = \frac{1 - 3 \cdot 2}{8}$

Step 5

Simplify the numerator.

Multiply $- 3$ by $2$ .

$v = \frac{1 - 6}{8}$

Subtract $6$ from $1$ .

$v = \frac{- 5}{8}$

Step 6

Move the negative in front of the fraction.

$v = - \frac{5}{8}$

Step 7

The result can be shown in multiple forms.

Exact Form:

$v = - \frac{5}{8}$

Decimal Form:

$v = - 0.625$
