The fraction of the reading assignment done by Tuesday night is 1/2.

<h3>What are fractions?</h3>
  • Fractions are the numbers that make up a portion of the whole. An object or a collection of objects can be a whole.
  • If a quantity or item is divided into equal pieces, each piece will represent a portion of the entire.
  • A fraction is represented by the ratio a/b, where a represents the numerator and b is the denominator.

Given:

Let the total reading assignment be x.

Fraction of the reading assignment finished by Tori on Monday afternoon = (1/6)x

Fraction of the reading assignment finished by Tori on Tuesday afternoon = (1/3)x

The fraction of the reading assignment done by Tuesday night is,

Total - Fraction of the reading assignment completed by Tori

= x -(\frac{x}{6} + \frac{x}{3} )

= x -(\frac{x+ 2x}{6}  )

= x - \frac{3x}{6}

= x -\frac{x}{2}

= \frac{2x-x}{2}

= \frac{x}{2}

So, 1/2 of the reading assignment(x) was done by Tuesday night.

Why does the equation 9−2x−9−16x=−14x−7−4x−11 have no solutions?
DENIUS [597]

Answer:

Because if you add 18x to both sides of the equation, you get 0 = -18

Step-by-step explanation:

When you combine like terms in the equation, you get -18x = -18x - 18. After adding 18x to both sides, you have 0 = -18. This is not true, which means that there are no solutions to the equation.
