how do you change Density= mass/volume (D=m/v) to solve v or m?

cross multiply!

D/1=m/v
dv=m

thank you

To change the formula Density = mass/volume (D = m/v) to solve for either volume (v) or mass (m), you need to rearrange the formula by isolating the desired variable on one side of the equation.

1. Solving for volume (v):
To solve for volume (v), rearrange the equation as follows:
D = m/v

Multiply both sides of the equation by v:
D * v = m

Divide both sides of the equation by D:
v = m / D

Therefore, the formula to solve for volume (v) is v = m / D.

2. Solving for mass (m):
To solve for mass (m), rearrange the equation as follows:
D = m/v

Multiply both sides of the equation by v:
D * v = m

Therefore, the formula to solve for mass (m) is m = D * v.

By rearranging the formula, you can solve for either volume (v) or mass (m) depending on which variable you want to find.
