Answer:
Either 3/80 grams or 0.0385 grams
Step-by-step explanation:
1 tablet = 1/40 of a gram
1/40 of a gram = 1 ÷ 40 = 0.025 grams
1 tablet = 0.025 grams
1.5 tablets = x
1/1.5 = 0.025 / x Cross multiply
x*1 = 0.025 * 1.5 Combine the factors
x = 0.0375 grams Convert to a fraction
0.0375 = 3/80
One sixth of an hour is 10 minutes.
That means it costs 5,700 every 10 minutes.
Costs 5,700 = 10 minutes
Dive 10 on both sides.
Costs 570 = 1 minute
Lets convert the minute into seconds.
Costs 570 = 60 seconds
Divide both sides by 60.
Costs 9.5 cents = 1 second
Round it off since you can't pay 9.5 cents.
Costs 10 cents = 1 second
This means that every second they pay 10 cents for the hotel. :D

Do 4x5, that is all you need to do, did you learn fractions in elementary?
Answer:
- 39/8y
Step-by-step explanation:
First you need to find a common denominator:
There is already a y in both denominators, so you don't have to worry about that. Since only one denominator has an 8, the other needs to have an 8, so you need to multiply the first fraction by 8 → - 4/y * 8 = - 32/8y
From here you can subtract the numerators:
- 32/8y +(- 7/8y) = - 39/8y
Because you are adding a negative to a negative, it makes the number mroe negative
I hope this helps!
