Answer:
1/3 of the original
Step-by-step explanation:
one piece is TWO times longer than the other one. if you break it in half you have three pieces that are all the same size
L*W*H , So 4*4*4, So therefore it would be 64 m3
Let x = the unknown number.
Because three-sevenths of the number is 21, therefore
(3/7)x = 21
That is
(3x)/7 = 21
Multiply each side by 7.
3x = 21*7 = 147
Divide each side by 3.
x = 147/3 = 49
Answer: 49
