3:4,5:2.4 2.4/4*5= 3 (8/4= 2 2*5=10) and 3/2*3= 4,5 (10/2*3=15)
Multiply 1/6 by 3 =1/2
In 3 days she would have completed 1/2 of the scarf.
First equate 4x+7y=3x,
we get, x+7y=0 ---->equ 1
Now equate 3x=y-2, we get 3x-y=-2 ----->equ2
solve equ 1,2,
We get x= -7/11, y=1/11
If this is the type of problem I’m thinking of it would be 26
