Answer 1

Answer:

A=83−72

= \LARGE\frac{21 - 16}{56}=5621−16 = \LARGE\frac{5}{56}=565

B = \LARGE \frac{3}{8} - \frac{1}{7 }B=83−71

= \LARGE\frac{21 - 8}{56}=5621−8 = \LARGE\frac{13}{56}=5613

C= \LARGE\frac{2}{8} - \frac{1}{7}C=82−71

= \LARGE \frac{14 - 8}{56}=5614−8 = \LARGE\frac{6}{56}=566

\LARGE\frac{5}{56} : \frac{13}{56} : \frac{6}{56} : \frac{4}{7}565:5613:566:74

= \LARGE \frac{5:13:6:32}{56}=565:13:6:32

= 5:13:6:32=5:13:6:32
