What is the correct method to label a segment with endpoint E and endpoint F? 
Degger [83]

Answer : option B

the correct method to label a segment with endpoint E and endpoint F

The endpoints of the line are E  and F

The Line starts at  E  and ends at F. The line will not extend after F

The line having end points are called as line segment

We represent a line segment by putting a line at the top

to label a segment with endpoint E and endpoint F, we use EF  or FE and a line at the top

So answer is option B

Whats the answer to these? (These are called Proper fractions.)
Darya [45]

Answer to the first question: 7/10ths of a mile

Explaination: When adding fractions, you need to have a common denominator. Since dividing 3/10 by 2 to get a denominator of 5 makes 3 a decimal, it's easier to multiply 2/5 by 2 to get a denominator of 10. You do the same to the top that you do to the bottom: \frac{2*2}{5*2} = \frac{4}{10}. From there, just add 4/10 and 3/10 to get the answer: 7/10ths of a mile.

Answer to the second question: Daniel read three (3/10) more books

Explaination: Since you can't evenly multiply 5 or 2 to get the opposite number, it's easier to multiply to the lowest common multiple. The easiest way to find that is to multiply both denominators (5*2=10). You'll have to multiply the numerator by the same amount you multipled the denominator by. For Daniel, that would mean: \frac{4*2}{5*2} = \frac{8}{10}. For Edgar, that would mean: \frac{1*5}{2*5} = \frac{5}{10}. So, Daniel read 3 more books than Edgar.

Answer to the third question: 2/4 mile (or 1/2 a mile)

Explaination: 2/8 can be simplified, by dividing the top and bottom by 2, resulting in 1/4. Since both fractions have the same denominator (/4), you can add them to get 2/4ths. This can be simplified further to half (1/2) a mile.

BRAINLIST AND 30 POINTS
svetlana [45]

Answer:

1/16

Step-by-step explanation:

So if you want to divide an amount equally, you divide the numbers. In this scenario, what you would do is this:

1/2 needs to be split 8 times

(1/2)/8

If you have something like this where the numerator is a fraction, then you multiply 2x8. that gives you 16, so now you add the 1 on top and you get 1/16.
