buns. On Thursday he used 1 3/4 times as many hot dog buns as on
Wednesday. How many bags of hot dog buns did Nate use on Thursday?
Simplify your answer and write it as a proper fraction or as a whole or mixed number.
When you read this, you immediately get this feeling that the answer is
(1 and 3/4) times (5). The only problem is that its kind of messy to
try and do the multiplication with (1 and 3/4) in that form, so its a lot
easier if you change it to a different form. you dont change the value
of the number, you just write it differently.
In place of (1 and 3/4), you could use 1.75, or you could use 7/4.
Theyre both exactly the same amount as (1 and 3/4), but they look
different, and theyre easier to work with.
Since the problem wants the answer as a fraction or mixed number,
lets use 7/4 in place of (1 and 3/4).
OK. Five bags were used on Thursday, and (7/4) of that many were used
(7/4) x (5 bags) = 35/4 bags. Thats the improper fraction.
The mixed number is (8 and 3/4) bags.
