Sally has a piece of cloth used 1/3 of a foot of the cloth to make a pillow cover in another 4/7 of a foot of the cloth to make

iren [92.7K]

Answer:

$\frac{23}{21} feets$

Step-by-step explanation:

Given.

Sally started with two feets of cloth.

Total cloth = $2 feets$

She used $\frac{1}{3}$ of a foot of the cloth to make a pillow cover.

And another $\frac{4}{7}$ of a foot of the cloth to make a table cloth.

She used total cloth to make a pillow cover and table cloth = $\frac{1}{3} +\frac{4}{7}$

$=\frac{7+12}{21} \\=\frac{19}{21}$

Total used cloth by Sally = $\frac{19}{21}$

The equation for remaining cloth

remaining cloth = total cloth - used cloth

remaining cloth $= 2 - \frac{19}{21}$

remaining cloth $= \frac{2\times 21-19}{21}$

remaining cloth $= \frac{42-19}{21}$

remaining cloth $= \frac{23}{21}$

Sally has remaining cloth = $\frac{23}{21}$ feets
