Answer:
I'm pretty sure it's number 2 although I think you meant milk spoiling and that's a chemical change
You're thinking b=1 will always give an integer, certainly true.
Then you think b=-1 will also always give an integer, so
Answer: ±1
Then you remember that a/b may not be a reduced fraction, so other bs beside the unit make give integers. The condition for an integer is
b | a
read 'b divides a' meaning a is a multiple of b.
Then you realize that a and b might not even b integers themselves.
Let's say the above answer is correct with the additional criteria that a and b are integers with no common factors.
4/5(8)= 32/40
5/8(5)= 25/40
You have to get the same denominator to be able to subtract so multiply one fractions denominator by the other so it becomes the same, and vise versa.
32/40-25/40= 7/40 which cannot be simplified.
Answer= 7/40 greater than the width.
Answer:
1 : 656250
Step-by-step explanation:
It is given that we need to dissolve 8 tablets of active ingredient B, each containing 3 mg, in 15,750 mL.
Tablets = 8
Weight of each tablet = 3 mg
Total wight of tablets = 8 × 3 = 24 mg
Total volume = 15,750 mL.
1 mL = 1000 mg
Total volume = 15,750000 mg
We need to find the ratio strength (w/v).
Therefore, the ratio strength (w/v) is 1 : 656250.
