Since 1-7/8=1/8, you have to also subtract 9-3=6. But since there is a fraction, you have to take away and extra one since if it was six it would be too big if you tried to add it back to 3&7/8. It would equal out to 10, so the answer is 5&1/8. If you add that up it equals 9.

You take 9 times 8 which is 72out of 9 and subtract 3 which is 7 and 7/8 out of 7 is 6 and 1/8

Hello, maybe you could please take 5 minutes out of your day to help me please :) id really appreciate it!

Vadim26 [7]

Answer:

D

Step-by-step explanation:

Alright, so we know that they can unload 25 trucks in 5 hours.

If we do 25/5 We find out that they can unload <u>5 trucks per hour</u>

Unfortunately, that is not one of the answers, so we will have to do some investigating to find something that is <u>equivalent</u>!

After evaluating the available answers, you can find that answer D lines up with our first assumption!

Every 1/5th of an hour the Fast-Pack people can unload a truck!

We can calculate this by writing:

1/5*25=<u>5</u>

<u></u>

Please let me know if you have any confusion! :)

After a 15% increase, a town has 115 people. What was the population before the increase?

Arte-miy333 [17]

Answer:

100 people

Step-by-step explanation:

<em>Population</em><em> </em><em>Of</em><em> </em><em>People</em><em>=</em><em>1</em><em>1</em><em>5</em><em>Percentage</em><em>ncrease</em><em>=</em><em>1</em><em>5</em><em>%</em>

<em>The</em><em> </em><em>New</em><em> </em><em>Population </em><em>corresponds </em><em>to</em><em> </em><em>1</em><em>1</em><em>5</em><em>%</em>

<em>(</em><em>That</em><em> </em><em>is</em><em> </em><em>1</em><em>0</em><em>0</em><em>+</em><em>1</em><em>5</em><em>)</em>

<em>We</em><em> </em><em>want</em><em> </em><em>to </em><em>find</em><em> </em><em>the</em><em> </em><em>popula</em><em>tion</em><em> </em><em>that</em><em> </em><em>corresponds</em><em> </em><em>to </em><em>100%</em><em> </em><em>that </em><em>is </em><em>the</em><em> </em><em>original</em><em> </em><em>population</em><em>.</em>

<em>Therefore</em><em> </em><em>Original </em><em>Population</em><em>;</em>

<em> $\frac{100}{115}\times {115}{}$ </em>

<em> $100 \: people$ </em>
