Answer:
7/5 y = y + 2/5 y
0.68 y = y - 0.32 y
3/5 y = y - 2/5 y
1.32 y = y + 0.32 y
Step-by-step explanation:
7/5 = 1 + 2/5 = 5/5 + 2/5
0.68 = 1 - 0.32
3/5 = 1 - 2/5 = 5/5 - 2/5
1.32 = 1 + 0.32
7/5y=y+2/5y
0.68y=y-0.32y
3/5y=y-2/5y
1.32y=y+1.32y
64/(1+1+2)
= 64/4
= 16
1 : 1 : 2
mark = 1×16 = 16
dave = 1×16 = 16
ralph = 2×16 = 32
12/12
6/12= 1/2
so 1/2+1/2 = One Whole and that the same thing as 12/12
