Salut.Nu imi mai amintesc prea bine cum se calculau fractiile cu intregi...ma puteti ajuta va rog? Ex:8intregi si 11/24-6intregi si 1/4



Răspuns :

8 intregi si 11/24=(24*8+11)/24=203/24
regula este a[tex] \frac{b}{c} [/tex]=[tex] \frac{c*a+b}{c} [/tex]
6[tex] \frac{1}{4} [/tex]=[tex] \frac{4*6+1}{4} [/tex]=[tex] \frac{25}{4} [/tex]
[tex]8 \frac{11}{24} -6 \frac{1}{4} = \frac{8*24+11}{24} - \frac{6*4+1}{4} = \frac{203}{24} - \frac{25}{4} =[/tex]

[tex]\frac{203}{24} - \frac{150}{24} =\frac{53}{24} =2 \frac{5}{24} [/tex]
