54 ASTRONOMICAL ANDA 
If the dividend and divifor, in the foregoing operation, be 
~“ leffened in the fame proportion, or, like parts, be taken inftead 
of their wholes, as;.if one fixth part of the former dividend be 
_ divided by one fixth part of the former divifor, the quotient 
and anfwer will be the fame as before. But the product of 
the two laft terms in the ftating (omitting the multiplication 
by. the third term 6) is equal to one fixth of {aid dividend :— 
Therefore, if the product of faid two laft terms be divided by 
200, equal to one fixth of the former divifor, the quotient 
and anfwer will be as before. Thus,

If inftead of the dividend 11920, in the laft operation, being 
divided by 200, it be divided by one of the two numbers, e. g. 
.10 and 20, the rectangle whereof is equal to 200, the divifor 
there, and the quotient thence arifing be divided by the other 
of faid two numbers, the laft quotient and anfwer will be the 
fame as before. thus;
