Answer:

\frac{ - 5}{54}  +  \frac{5 \times 6}{9 \times 6}  =  \frac{ - 5 + 30}{54}  =  \frac{25}{54}

\frac{15}{4}   \div  \frac{3}{8}  =  \frac{15}{4}  \times  \frac{8}{3}  =  10

10 \times  \frac{25}{54}  =  \frac{250}{54}  = 4 \times \frac{17}{27}

b )

4 \times \frac{17}{27}  =  \frac{125}{27}  =

cube root =

\frac{5}{3}

c ) square root

\frac{125}{27}  =  \frac{ \sqrt{25 \times 5} }{ \sqrt{3 \times 9} }  =  \frac{5 \sqrt{5} }{3 \sqrt{3} }

A STORY OF UNITS
Nikitich [7]

In the remaining part of the semester, Zachery wrote an average of 10,000 words per month to complete his final project for the course.

We are given that Zachery has to write a total of 95,234 words.

Total words to be written = 95,234 words.

Words already written in the first month = 35,295 words.

Words already written in the second month = 19,240 words.

Words written in total = 35,295 words + 19,240 words.

= 54,535 words

Words left for writing = 95,234 words - 54,535 words

= 39,699 words

months left = 4

Average Words written in remaining month = 39,699 words / 4

= 9924.75 words.

= 10,000 words.

Therefore, in the remaining part of the semester, Zachery wrote an average of 10,000 words per month to complete his final project for the course.
