The correct equation of 146 ÷ 7 = 20857 is 146.0 ÷ 7.0 = 20.857

<h3>How to divide the decimals?</h3>

The equation is given as:

146 ÷ 7 = 20857

The above equation is wrong.

The equation can be rewritten as:

146.0 ÷ 7.0 = 20857

The significant digits in 146.0 and 7.0 are 3 and 1, respectively.

3 - 1 = 2

This means that

So, the decimal place in the result must be after the second digit.

So, we have:

146.0 ÷ 7.0 = 20.857

Using the above highlights, we have:

146 ÷ 0.7 = 208.57

1.46 ÷ 7 = 0.20857

14.6 ÷ 0.7 = 20.857

1460 ÷ 70 = 20.857

The reasoning behind the above equations is that the decimal position in the results is dependent on the decimal positions in the dividend and divisor

The LCD for the fractions 1/3, 3/4, 5/32, and 8/9 is

tresset_1 [31]

What is the smallest number divisible by 3, 4, 32 and 9?
You might want to try factoring these denominators and writing them in their factored form:

3, 2^2, 2^5, 3^2

Your LCD must include the following factors: 3^2 and 2^5, or 9 and 32. Multiplying these together results in the correct LCD 9*32=288.

Check: Is 288 divisible by 3? Yes. The quotient is 96.
Is 288 divisible by 4? Yes. Is 288 divisible by 32? Yes. Is 288 divisible by 9? Yes.

The sum of three numbers $x$ ,$y$, $z$ is 165. When the smallest number $x$ is multiplied by 7, the result is $n$. The value $n$

babymother [125]

You're given

x + y + z = 165

7x = n

n = y - 9

n = 9 + z

and you want to find xyz.

Solve the last three equations for x, y, and z :

7x = n → x = n/7

n = y - 9 → y = n + 9

n = 9 + z → z = n - 9

Substitute x, y, and z into the first equation and solve for n :

n/7 + (n + 9) + (n - 9) = 165

n/7 + 2n = 165

n + 14n = 1155

15n = 1155

n = 77

Now solve for x, y, and z :

x = 77/7 = 11

y = 77 + 9 = 86

z = 77 - 9 = 68

Then the product is

xyz = 11 • 86 • 68 = 64,328

To find the area of the sides do length times width so
4x1
and 1x1
There are four of the 4x1
and two or the 1x1
so 4x4=16 and 1x2=2
16+2=18
