Answer:
1) 3/4
2) 15 days
Step-by-step explanation:
A has completed 3/12 = 1/4 of the work
3/4 of the work is left to be done
B can do the work in 20 days.
Since 3/4 of the work is left,
He needs (3/4)×20 = 15 days to complete the remaining work

1 cookie=number/number where number stays constant so
1 cookie=1/1,2/2,3/3,4/4,5/5, etc
so if 3/4 of cookie eaten
the bottom number tells how many in the whole or 1 so
whole=4/4
4/4-3/4=1/4
1/4=not eaten
equivilent, multiply top and bottom number by same number
1/4 times 2/2=2/8
1/4 times 4/4=4/16
Geometric mean= √ ( 1/2 X 2/5 )
= 1/√5
