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

<h3>The equation is:</h3><h3>
</h3><h3>The number is 3 or 4</h3><h3><em><u>Solution:</u></em></h3>
Given that,
7 added to the square of a number is equal to 7 times the number, minus 5
Let "x" be the unknown number
From given,
7 added to square of x = 7 times the x minus, 5
Solve the above equation
Split the middle term
We have two solutions
x - 3 = 0
x = 3
And
x - 4 = 0
x = 4
Thus number is 3 or 4
Can we see the options plz
