<h3>Answer: 60 grams</h3>

========================================================

Explanation:

m = mass

v = volume

d = density

The formula we use is

d = m/v

Multiplying both sides by v allows us to solve for m

d = m/v

d*v = m

m = d*v

Now plug in the given density (d = 4) and the given volume (v = 15) and simplify:

m = d*v

m = 4*15

m = 60 grams

Note how,

d = m/v

d = 60/15

d = 4

which helps confirm our answer

Which of these is equal to ⅔ × ¾ × ⅗?

Sphinxa [80]

Answer:

3/10

Step-by-step explanation:

Just multiply all of the numerators (top numbers) and then multiple all of the denominators (bottom numbers)

2/3x3/4x3/5 would be 18/60 Then take any number that is a factor to both 18 and 60 and divide both numbers by that factor. I could use 2 or 3 or 6 because both 18 and 60 is divisible by any of these numbers. I will choose 3. I will divide the top and bottom of 18/60 by 3 to get 6/20, now I will divide the top and bottom of that number by 2 to get 3/10
