# how to reduce a fraction

To reduce a fraction, you simply need to find out if the numerator and the denominator have a common divisor, and if so, then divide that divisor it out. For example, say you have the following fraction: $\frac{42}{86}$ We can tell just by looking at this fraction that both numerator and denominator are divisible by 2, since they are both even numbers. So when we divide the two out, we are left with $\frac{42 / 2}{86 / 2} = \frac{21}{43}$ So the fraction $\frac{42}{86}$ reduces to $\frac{21}{43}$. Hope that helped! =)
