Question

calculati:
[tex] a) \frac{3}{4}+ \frac{5}{8}
b)\frac{7}{8}+ \frac{1}{2}
c)\frac{1}{2}+ \frac{1}{4} [/tex]

Answer 1

A) 3\4+5\8=6\8+5\8=11\8
B)7\8+1\2=7\8+4\8=11\8
C)1\2+1\4=2\4+1\4=3\4
\--> linia de fractie

Answer 2

[tex] \frac{3}{4}+ \frac{5}{8}= \frac{3*8+4*5}{32} = \frac{44}{32}; \frac{7}{8}+ \frac{1}{2}= \frac{7*2+8*1}{16} = \frac{22(2}{16}= \frac{11}{8} ; \frac{1}{2}+ \frac{1}{4}= \frac{1*4+1*2}{8}= [/tex]
$\frac{6(2}{8}= \frac{3}{4}$
BAFTA!!
