How do you solve #\frac { 49} { c } = \frac { 98} { 92}#?

Answer 1

Genesis Amaya

#49/c=98/92 => c=46#

Cross Multiplication

#49/c=98/92 <=> 49(92)=98c#

Divide both sides by #98# then you get

#((49)92)/98=c#

Because #98=49(2)# we can cancel out 49s

#=92/2=c#

Then

#c=46#

To solve the equation (\frac{49}{c} = \frac{98}{92}), first, cross multiply to eliminate the denominators. Then, solve for (c).

[49 \times 92 = 98 \times c]

[c = \frac{49 \times 92}{98}]

[c = \frac{4508}{98}]

[c = 46]

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.
