Question

Simplificati fractiile :
$\frac{5200}{18200}$
$\frac{1716}{4290}$
$\frac{72a}{108a}$
$\frac{34a+34b}{51a+51b}$
$\frac{2⁷*3²*5⁴}{2⁷*3³*5²*11}$

Answer 1

5200/18200=2⁴x5²x13/2³x5²x7x13=2/7
1716/4290=2²x3x11x13/2x3x5x11x13=2/5
72a/108a=72/108=2³x3²/2²x3³=2/3
(34a+34b)/(51a+51b)=34(a+b)/51(a+b)=34/51=2x17/3x17=2/3
2⁷x 3² x 5⁴/ 2⁷ x 3³ x 5² x 11=5²/3x11
