It is a false statement.
385/100 = 77/20, or 3 17/20
20/21
2/5 + 3/4 - 1/2 equals 8/20 + 15/20 - 10/20 which adds up to 8/20 This equals 4/5
3/20 + 1/10 is the same as 3/20 + 2/20 which equals 5/20 which turns out to be 1/4 or 0.25 in decimal
7/20 + 3/9 = 41/60
The answer is 20. In each addition, the individual digits are added together (1+2+3+5+4 = 15)
If: 4 = 3/5s Then: s = 3/20
20 = 5 + n/3 15 = n/3 n = 45
6/11 + 3/7... 6/11 = 42/77 & 3/7 = 33/77 42/77 + 33/77 = 75/77
77
0.15
2/3 equals 20/30 7/10 equals 21/30 2/3 is less than 7/10.
