Elements of N should be like {6,7}
There are 16 oz per 1 lb. multiply 10 by 16 (to convert your lbs into oz) =160. Then divide that by 8 (to figure out how many 8oz bags it would fill) =20 bags. Or since each bag you want to fill is half a lb multiply the number of lbs by 2, which would also give you 20 :)
Solution:
Given expression is
To solve this expression:
Using algebraic identity:
We can't solve it with division symbol. So change this into multiplication and solve it.
The second term is reversed when you change division into multiplication.
Now, cancel the common terms in the numerator and denominator.
Hence the answer is .
Answer:
1 3/5
Step-by-step explanation:
(4 cans)/(2 1/2 qt) = (4 cans)/(5/2 qt)
= (4)·(2/5) cans/qt . . . . . . . "invert and multiply"
= 8/5 cans/qt
= (5 +3)/5 cans/qt
= (5/5 + 3/5) cans/qt
= 1 3/5 cans/qt
_____
You can also think of this as multiplying the following statement by 2/5:
... 4 cans for 5/2 quarts
... (4)(2/5) cans for (5/2)(2/5) quarts . . . . multiply by 2/5
... 8/5 cans for 1 quart . . . . simplify
... 1 3/5 cans for 1 quart . . . . write improper fraction as mixed number
