Answer:
Sam made 45 rolls
Step-by-step explanation:
After giving some to his neighbor, Sam has 1 -2/5 = 3/5 of the original quantity left. After giving some to his cousin, he has (3/5)(1 -4/9) = (3/5)(5/9) of the original quantity left.
(3/5)(5/9) = 3/9 = 1/3
15 rolls = (1/3)·(original number) . . . . . . Sam has 15 roll left
45 rolls = original number . . . . . . . . . . . multiply by 3

<em>Check</em>
Same gave 2/5·45 = 18 rolls to his neigbor, so had 27 left. Sam gave 4/9·27 = 12 to his cousin, so had 15 left.

Step-by-step explanation:
hope this is right...
Area : Multiply the two numbers
13*8=104 yd^2
Perimeter: Add the two numbers two times
Perimeter : 13+8+13+8=42 yd
Answer:
Area is 104yd^2
Perimeter is 42yd
3/4=15
let,
total mass is x
x=4×15/3
=20 kg
so, total mass = 20 kg
=2×20/5
=2×4
=8 kg
Hope this helps!
