Express 4/5 as a decimal using long division

Mathematics
1 answer:
Hoochie [10]1 year ago
5 0

Here, we want to express the given fraction as a decimal by the use of long division

We start by writing the long division sign

We place 5 on the left hand side outside and place 4 inside the long division sign

Now, as we know, 4 cannot divide 5 wholly as it is less than 5

We simply add a 0 at the top of the long division symbol, with a decimal point after it.

Concurrently, we place a zero after 4

Hence we have 40 inside the long division

Then we can divide 40 by 5 to get 8

The 8 now comes after the decimal point

Hence, our answer is 0.8

Pictorally, we can have the representation as follows;

Write the number five million four thousand three hundred in standard form
valentinak56 [21]

Written numerically, the number you stated is written as:

5,004,300

Standard Form (Scientific Notation) numbers are written as a decimal (n.m) such that there is [normally] only one digit (n) to the left of the decimal point, and the rest of the number (m) to the right (with a possible limit). If there is only a single digit in the whole number then the value on the right is a zero (n.0).

To show that the value shown has shifted its decimal point position, the number of decimal positions shifted is shown after the number as a 10’s multiplied to the power of the number of positions shifted.

e.g., 102 = 102.0 = 1.02 (decimal point shifted left two places. If smallest digit is 0 then ignore it UNLESS it’s the ONLY digit!!)

1.02*10^2(2 Decimal shift to the left)

1.02*10^2

So, for the number asked in the question:

5,004,300 = 5,004,300.0

Left shift 6 times to largest digit = 5.004300

5.004300 (show the shift multiplier: 10^6)

5.004300*10^6

Solve -2a-5&gt;3. which graph shows the solutions?<br>​
Flura [38]

Answer:

see explanation

Step-by-step explanation:

Given

- 2a - 5 > 3 ( add 5 to both sides )

- 2a > 8

Divide both sides by - 2, reversing the direction of the inequality sign as a consequence of dividing by a negative quantity

a < - 4

Since a is less than we require an open circle at - 4 on the number line.

Since less than the arrow head is pointing to the left, that is

Graph A, the top graph illustrates the solution

Gwar [14]

Answer:

\frac{3}{2a}  +  \frac{1}{6a}  \\  \\  \frac{9}{6a}  +  \frac{1}{6a}  =  \frac{9 + 1}{6a}  \\  \\  =  \frac{10}{6a}  =  \frac{5}{3a}

I hope I helped you^_^
