How do you solve #4/10 = n/15#?

Answer 1

Savannah Anderson

#6 = n#

#4/10 = n/15#

Simply cross multiply

#(15)(4) = 10(n)#

#60=10n#

Isolate the variable by dividing both sides by 10.

#60/10 = ((cancel10)n)/cancel10#

#6 = n#

To solve the equation ( \frac{4}{10} = \frac{n}{15} ), you can cross multiply:

( 4 \times 15 = 10 \times n )

Then solve for ( n ):

( 60 = 10n )

Divide both sides by 10:

( \frac{60}{10} = \frac{10n}{10} )

( 6 = n )

So, ( n = 6 ).

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.
