Answer 1

sumas y restas de fracciones

$\frac{6}{25} -\frac{2}{5}$

25 x 2 = 50

6 x 5 = 30

25 x 5 = 125

$\frac{6}{25} -\frac{2}{5}= \frac{50 - 30}{125} = \frac{30}{125}$

$\frac{30}{125} + \frac{7}{50}$

30 x 50 = 1500

125 x 7 = 875

125 x 50 = 6250

$\frac{30}{125} + \frac{7}{50} = \frac{1500+875}{6350}=\frac{9375000}{6350}$
