write the fraction $\frac{21}{49}$ in simplest form.
Answer
Explanation:
Step1: Find the GCD of 21 and 49
We need to find the greatest - common divisor of 21 and 49. The factors of 21 are 1, 3, 7, 21. The factors of 49 are 1, 7, 49. The GCD of 21 and 49 is 7.
Step2: Divide both numerator and denominator by the GCD
Divide 21 by 7 and 49 by 7. $\frac{21\div7}{49\div7}=\frac{3}{7}$
Answer:
$\frac{3}{7}$
