8 0

Answer:

  6 7/8

Step-by-step explanation:

Take a quick look at those fractions.  The LCD here is 8.  We'll leave 4 5/8 as is, but change 2 1/4 to 2 2/8.

Now we'll add together:

 4 5/8

+ 2 2/8

-----------

  6 7/8

6 \frac{7}{8}.

The easiest way to solve this problem is to sum the whole number and the fractions separately.

4\frac{5}{8} + 2\frac{1}{4}\\\\4\frac{5}{8} + 2 \frac{1}{4}(\frac{2}{2})\\\\4\frac{5}{8} + 2\frac{2}{8}

Solving the sum:

4\frac{5}{8} + 2\frac{2}{8} = 6 \frac{7}{8}

Four points partition the directed line segment from A to B. • Point P partitions the directed line segment from A to B into a 3
Alecsey [184]

Answer:

S is closest to B.

Step-by-step explanation:

Given a directed line segment from point A to B.

Point P divides the line A to B in a ratio 3:4.

Point Q divides the line A to B in a ratio 4:3.

Point R divides the line A to B in a ratio 2:5.

Point S divides the line A to B in a ratio 5:2.

To find:

The point which is closest to the point B.

Solution:

Here, to find the point closest to B we need to find the distances PB, QB, RB and SB.

We can see the sum of ratio 3:4, 4:3, 2:5 and 5:2 is 7.

Let the distance between A and B be 7 units.

Now, the distances can be found easily.

PB = \dfrac{4}{7}\times 7 = 4\ units

QB = \dfrac{3}{7}\times 7 = 3\ units

RB = \dfrac{5}{7}\times 7 = 5\ units

SB = \dfrac{2}{7}\times 7 = 2\ units

The point which has the minimum distance from point B, will be nearest to B.

We can clearly observe that SB is the minimum distance.

Therefore, <em>S is closest to B</em>.
