In the stock market an amazon stock share rose 4 and 1/2 points on Wednesday rose 3 and 3/8 points on Thursday and fell 2 and 1/

Vika [28.1K]

Answer:

In the three days the Amazon stock share rose by $5\frac{5}{8}$

Step-by-step explanation:

Given:

Amazon stock share

rose 4 and 1/2 points on Wednesday

rose 3 and 3/8 points on Thursday

fell 2 and 1/4 points on Friday

To find the overall change.

Solution:

<em>The change in share on Wednesday is given as = $+4\frac{1}{2}$ </em>

<em>The change in share on Thursday is given as = $+3\frac{3}{8}$ </em>

<em>The change in share on Friday is given as = $-2\frac{1}{4}$ </em>

Thus, the over all change is given by:

$4\frac{1}{2}+3\frac{3}{8}-2\frac{1}{4}$

<em>In order to combine mixed numbers, we will work the whole numbers and the fractions separately.</em>

⇒ $(4+3-2)+(\frac{1}{2}+\frac{3}{8}-\frac{1}{4})$

⇒ $5+(\frac{1}{2}+\frac{3}{8}-\frac{1}{4})$

To combine fractions, we will take least common denominator.

<em>The L.C.D. 2,4 and 8 = 8 as it is the least common multiple for all the denominators</em>

So, we multiply the numerators with the corresponding numbers to make the denominators common.

⇒ $5+(\frac{1\times 4}{2\times 4}+\frac{3}{8}-\frac{1\times 2}{4\times 2})$

⇒ $5+(\frac{4}{8}+\frac{3}{8}-\frac{2}{8})$

Combining the numerators.

⇒ $5+\frac{4+3-2}{8}$

⇒ $5+\frac{5}{8}$

⇒ $5\frac{5}{8}$

The overall change for the three days can be given as : $+5\frac{5}{8}$

This means the share rose by $5\frac{5}{8}$

Solve for u. 31.25 = u/5

ipn [44]

Answer:

u = 156.25

Step-by-step explanation:

Step 1: Write equation

31.25 = u/5

Step 2: Solve for <em>u</em>

Multiply both sides by 5: 156.25 = u
Rewrite: u = 156.25

Step 3: Check

<em>Plug in u to verify it's a solution.</em>

31.25 = 156.25/5

31.25 = 31.25
