Answer:

$\frac{-47}{6}$ = $7.833$

Step-by-step explanation:

Expression given is:

$-4\frac{2}{3} -(3\frac{1}{6})$

Now change the mixed fraction to improper fractions;

$-\frac{14}{3} -\frac{19}{6}$

Now take a common denominator:

$-\frac{28}{6} -\frac{19}{6}$

Now we can simplify the the above equation:

$\frac{-28-19}{6}$

$\frac{-47}{6}$ = $7.833$

Jennifer had 7/8 foot board she cut off 1/4 foot peice that was for a project.in feet how much board was left?

guapka [62]

$\frac{5}{8} \text{ feet board is left }$

<em><u>Solution:</u></em>

Given that, Jennifer had 7/8 foot board she cut off 1/4 foot peice that was for a project

To find: Board that was left

From given,

$\text{Total length of board } =\frac{7}{8} \text{ feet }$

$\text{Foot that was cut off } = \frac{1}{4} \text{ feet }$

Remaining feet of board is found by finding the difference between total length of board and foot that was cut off

$\text{Reamining board } = \text{Total length of board - feet of board that was cut off}\\$

Substituting the values we get,

$\text{Remaining board } = \frac{7}{8} - \frac{1}{4}\\\\\text{Remaining board } =\frac{7}{8} - \frac{1 \times 2}{4 \times 2}\\\\\text{Remaining board } =\frac{7}{8} -\frac{2}{8} = \frac{7-2}{8}\\\\\text{Remaining board } =\frac{5}{8}$

Thus $\frac{5}{8}$ feet board is left
