Make the divisor the whole number by 'moving' the decimal point all the way to the right. 'Move' the decimal point in the dividend the same number of places to the right.
Divide. Place the decimal point in the quotient above the decimal point in the dividend. Add zeros as needed until the remainder is zero.
Make the divisor a whole number by 'moving' the decimal point all the way to the right.
'Move' the decimal point in the dividend the same number of places.
Divide.
Place the decimal point in the quotient above the decimal point in the dividend.
Now we will divide a whole number by a
decimal number.
Divide:
$4\xf70.05.$
Solution
$4\xf70.05$
The signs are the same.
The quotient is positive.
Make the divisor a whole number by 'moving' the decimal point all the way to the right.
Move the decimal point in the dividend the same number of places, adding zeros as needed.
Divide.
Place the decimal point in the quotient above the decimal point in the dividend.
Write the quotient with the appropriate sign.
$4\xf70.05=80$
We can relate this example to money. How many nickels are there in four dollars? Because
$4\xf70.05=80,$ there are
$80$ nickels in
$\text{\$4}.$
We often apply decimals in real life, and most of the applications involving money. The Strategy for Applications we used in
The Language of Algebra gives us a plan to follow to help find the answer. Take a moment to review that strategy now.

Jeannette has $5 and $10 bills in her wallet. The number of fives is three more than six times the number of tens. Let t represent the number of tens. Write an expression for the number of fives.
why surface tension is zero at critical temperature
Shanjida
I think if critical temperature denote high temperature then a liquid stats boils that time the water stats to evaporate so some moles of h2o to up and due to high temp the bonding break they have low density so it can be a reason
