Franco is reading a book with 482 pages he reads 30 pages each night. how many pages will he read in 7 nights? show your work
Sergeu [11.5K]
The number of pages in the book is actually irrelevant.

Franco reads 30 pages in 1 night. To find how many pages he reads in 7 nights, just multiply by 7.

30*7=210

Franco reads 210 pages in 7 nights.


Solving with Equivalent Ratios:

The ratio of pages he reads per night is 30:1. We need to figure out the ratio <em>x</em>:7, where the variable <em>x</em> is the number of pages he reads in 7 nights.

30:1=<em>x</em>:7

To find x we need to see the similarity between both ratios. This is found by dividing two of the equal sides, here it would be 7 and 1.

7/1=7

This means that the second ratio is 7 times the first ration. To find <em>x</em>, just multiply 30 by 7.

30*7=210

Franco reads 210 pages every 7 nights.

Maria runs 7 miles in 80 minutes. at the same rate, how many miles would she run in 64 minutes​
Alex777 [14]

Answer:

5.6 miles

Step-by-step explanation:

Firstly, we need to find the unit rate (the number of miles in 1 minutes).

To get this, we need to divide total miles ran (7 miles) by the total minutes taken (80 minutes). Thus, we will have MILES PER MINUTE.

7 miles ÷ 80 minutes = 7/80 miles per minute

Now,

We want number of miles in 64 minutes. Since we know "PER MINUTE", we simply multiply that with 64 to get number of miles in that amount of time.

THus,

\frac{7}{80}*64=\frac{56}{10}=5.6

So, in 64 minutes, Maria can run 5.6 miles
