Answer:
The fraction of the book that Rena read every day is 
Step-by-step explanation:
Rena spent 6 days reading her book completing the same fraction of the book every day and you want to know the fraction of the book she read each day. Knowing that Rena had a total of 8/9 of her book read after 6 days, then you simply divide the total amount of the book read during those days by 6, the number of days:
÷6
To divide a fraction by a whole number, you must convert the whole number into a fraction, finding the reciprocal of that fraction, and multiply it by the first fraction. That is, you must find the reciprocal of the number that is after the division symbol; and then you multiply the first number (the one before the division symbol) by the reciprocal of the second number (the one after the division symbol). Remember that to find the reciprocal of a number, you simply have to change the numerator and denominator of the number.
Since 6 can be considered to be a fraction equal to 
, by inverting the number, then you get 
Then:
÷6= 
Now you multiply the numerators and denominators of the fraction to get the new numerator and denominator of the final solution.
÷6= 
Finally, simplifying the fraction:
÷6= 
So:
÷6=

Answer:
They have 83 dogs and 50 birds.
There are 133 animals in total in the shelter.
Step-by-step explanation:
So let's call the dogs D and the birds B.
D = 25% + B
What ever the amount of animals, the total for D must always be 25% more than B.
To get 100% of the animals, B must equal 37.5% and D must equal 62.5%.
The way I worked this out was:
100% - 25%= 75%
75% divided by 2= 37.5%
37.5% + 25%= 62.5%
And just to check
37.5% + 62.5% = 100%
So to work out 100%:
37.5% = 50
divide both by 37.5 to get 1%
1% = 1.333333
time both by 62.5 to get 62.5%
62.5% = 83.333313
We'll round that answer because I'm pretty sure they don't have a .333313th of a dog.
So D = 62.5% = 83
They have 83 dogs and 50 birds.
Phew! That was the hard part. Now onto something wayyy easier.
To get the total number of animals in the shelter we just do 83 + 50, which is 133.
There are 133 animals in total in the shelter.
Hope this helps you :)
Answer:
20
Step-by-step explanation:
Use <u>PEMDAS</u>
P = parenthesis
E = Exponents
M = Multiplication*
D = Division*
A = Addition**
S = Subtraction**
*either can come first, it just depends which comes first in the equation.
**either can come first, it just depends which comes first in the equation.
<em>Step 1 : Write equation</em> 4( 9 × 2 ) ÷ ( 4 -1 ) - 4
<em>Step 2: Solve in parenthesis </em>4(18) ÷ (3) - 4
<em>Step 3: Solve multiplication </em> 72 ÷ 3 - 4
<em>Step 4: Solve division </em>24 - 4
