The fraction of text -3/8 of the cover page
From this fraction of text only 2/5 of the text is about endangered species
We are asked to find out what the fraction of the cover page is that covers endangered species
In this 2/5 of 3/8 is about endangered species
Therefore to obtain the answer we need to multiply the two fractions
2/5 * 3/8
Fraction of the cover page about endangered species is therefore = 2/5 * 3/8
= 0.15

Answer:
63
Step-by-step explanation:
Reversing the digits changes the value by a factor of 9 times the difference in the digit values. Here, this means the digits differ by 27/9 = 3. If one digit is double the other, the higher digit is 2×3 = 6.
The number is 63.
_____
If you like, you can work through the algebra of it. Let the original number have tens digit x and ones digit y.
original number value = 10x +y
reversed number value = 10y +x
difference of values = 27 = (10x +y) -(10y +x) = 9(x -y)
The tens digit is twice the ones digit, so we have ...
x = 2y
Substituting in the difference equation, we have ...
27 = 9(x -y)
3 = (2y -y) = y . . . . . divide by 9, substitute for x
x = 2(3) = 6
The number is 10x+y = 63.
Answer:
<em>713,900</em>
Step-by-step explanation:
713,<u><em>9</em></u>49
The bold, italic, underlined digit is the hundreds digit.
To round to the nearest hundred, change all digits to the right of the hundreds digit to 0. Now you have
713,900
There is one more step. Look at the first digit that used to be to the right of the hundreds digit. If it is from 1 to 4, the hundreds digit remains the same. If it is from 5 to 9, the hundreds digit goes up by 1. In this case, the first digit to the right of the hundreds digit was 4, so the hundreds digit does not go up by 1.
