Question

Ajutațimă: 7/100 + 49/150 =

Answer 1

7/100+49/150= aducem la acelasi numitor
calculam c.m.m.m.c
100=2²·5²
150=3·2·5²
[100,150]=2²·3·5²=300
300:100=3 deci cu 3 amplificam I fractie
300:150=2 cu 2 amplificam a II fractie
avem(7x3+49x2)/300=(21+98)/300=119/300

Answer 2

$\frac{7}{100} + \frac{49}{150}$
$\frac{7}{100}$=$\frac{105}{1500}$ (se amplifica cu 15)
[tex] \frac{49}{150 } [/tex]=$\frac{490}{1500}$ (se amplifica cu 10)
$\frac{105}{1500} + \frac{490}{1500}= \frac{105+490}{1500}= \frac{595}{1500}$=$\frac{119}{300}$ (se simplifica cu 5)
