Step-by-step explanation:
Hey there!
To plot a fraction on a graph you have to turn it into an improper fraction. In this case, the improper fraction for 2 2/3 is 8/3 and the improper fraction for 1 7/9 is 16/9.
*Note: To find the improper fraction of a fraction you must multiply the denominator by the whole number and then add the numerator.
With these two improper fractions...
8/3
16/9 (Simplify it down to 8/3 since both 16 and 9 go into 3)
You can now graph it. To graph, the numerator tells you how many times to go up and the denominator tells you how many times to go right. <u>IF IT'S NEGATIVE IT WILL DO THE OPPOSITE</u><u> </u><u>IF THE NUMERATOR IS NEGATIVE IT WILL GO DOWN INSTEAD OF UP AND IF THE DENOMINATOR IS NEGATIVE IT WILL GO LEFT INSTEAD OF RIGHT.</u>
8/9 means you need to start at the origin, (0,0) and go 8 up and 3 to the right. 8/3 means you start at the origin and go 8 up and 3 to the right. You will almost always start at the origin.
I really hope this helps :)
Okay to find what 18+?=45 just subtract 18 from 45. ANSWER: 27
Answer:
15mg/ml
Step-by-step explanation:
Percent mass per volume ( % m/v) is unit expression that tells us how many grams of a solute that we can find 100 ml of a particular solution.
In the above question, we are asked to express 1.5%w/v Bepotastine besilate (BEPREVE) ophthalmic solution as mg/mL
Step 1
1.5% w/v = 1.5 g of Bepotastine besilate (BEPREVE) in 100ml ophthalmic solution
Hence, if
100ml = 1.5g
1 ml = y g
We Cross Multiply
100ml × yg = 1 ml × 1.5g
yg = 1 ml × 1.5g/100ml
= 0.015g
Therefore, in 1 ml we have 0.15 g.
Step 2
Since we are asked to express as mg/ml
We convert 0.015g to mg
1 gram = 1000 milligrams
0.015 grams =
Cross Multiply
0.015grams × 1000 milligrams/ 1 gram
= 15 mg
Therefore, the concentration in mg/ml of 15% m/v of Bepotastine besilate (BEPREVE) ophthalmic solution is 15mg/ml
