Factor 1/8 out of 1/8x-49/8​
svetoff [14.1K]

Answer:

1/8(x - 49)

Step-by-step explanation:

When we factor out something, we are basically finding common factors from multiple terms to take out. Example:

ab + ac; factored out: a(b + c)

If we want to factor out 1/8 from 1/8x - 49/8, we simply divide the two terms by 1/8.

\frac{1/8}{1/8x} The 1/8 cancel out giving us x so:

1/8(x - __)

The next term,

\frac{49/8}{1/8}

When two fractions divide, you flip the bottom one and multiply them both,

\frac{49}{8} *\frac{8}{1}

giving us 49.

The answer is: 1/8(x - 49)
