How do you solve #16/7=m/21#?

Answer 1

See a solution process below:

Multiply each side of the equation by #color(red)(21)# to solve for #m# while keeping the equation balanced:

#color(red)(21) xx 16/7 = color(red)(21) xx m/21#

#cancel(color(red)(21))color(red)(3) xx 16/color(red)(cancel(color(black)(7))) = cancel(color(red)(21)) xx m/color(red)(cancel(color(black)(21)))#

#color(red)(3) xx 16 = m#

#48 = m#

#m = 48#

To solve the equation 16/7 = m/21 for m, you can cross multiply and then solve for m:

16/7 = m/21 Cross multiply: 16 * 21 = 7 * m 336 = 7m Divide both sides by 7: 336 / 7 = m m = 48

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
