It is: 6/7
Yes, they are both divisible by nine, so: 6/7
1820 over 54 reduced = 910/27
54 over 100 can be reduced to 27/50
6/7 - 5/9... First make both fractions the same... 6/7 = 54/63 & 5/9 = 35/63 therefore... 54-35 = 19/63 which cannot be reduced any further.
54/63 = 6/7 simplified
54/63 is 6/7 in simplest form (six over seven)
Yes, 14 / 63 can be reduced to 2 / 9.
10/63 cannot be reduced any further.
54/78 = 9/13
No, it cannot.
6/7 x 9/9 = 54/63 80/9 x 7/7 = 560/63 54/63 + 560/63 = 614/63
