Question

What is \[142\] divided by \[18\]?

Answer 1

Hint: We need to find out the quotient from the given numbers by dividing.
There are four basic operations of arithmetic. The division is one of them.
The number that is being divided is Known as the dividend, which is divided by the divisor, and the result is called the quotient. The remainder is the number "leftover" after dividing one number by another to produce a quotient.
To find the quotient we first need to what is the dividend and what is the divisor then we will divide the dividend by the divisor and the result is the quotient.

Complete step by step answer:
We need to divide\[142\] by \[18\]and find out the quotient.
Hence, we need to find\[142 \div 18\].
Now we need to do a division operation.
Then we get
\[18\mathop{\left){\vphantom{1
  142 \\
  \underline {126} \\
  160 \\
  \underline {144} \\
  160 \\
  \underline {144} \\
  16 \\
 }}\right.
\!\!\!\!\overline{\,\,\,\vphantom 1{
  142 \\
  \underline {126} \\
  160 \\
  \underline {144} \\
  160 \\
  \underline {144} \\
  16 \\
 }}}
\limits^{\displaystyle \,\,\, {7.89}}\]
Here we see that after carrying division we return with a quotient \[7\]and remainder\[16\]. If we put it in decimal we will get,\[7.8888 \simeq 7.89\]
Thus,\[142 \div 18\]\[ \simeq 7.89\]

Note:
The rounding of a number can be executed by replacing a number with an approximate value that has a shorter, simpler, or more explicit representation.
Rounding rules for decimal numbers:
Find out the rounding digit and look at its right-hand side.
If the digits on the right-hand side are less than\[5\], we need to consider them equal to zero.
If the digits on the righthand side are greater than or equal to\[5\], then we need to add one to that digit and consider all other digits as zero.
For example, if we consider the following numbers, we will get the below approximate results,\[5.658 \approx 5.66\]
\[5.654 \approx 5.65\]
