For addition and subtraction the answer should have the same number of decimal places as the least number of decimal places involved in the operation. For multiplication and division the number of significant value of the answer should be the same as the least number of significant values of the involved numbers.
a. 26 x 0.02584 = 0.67
b. 15.3: 1.1 = 14
c. 782.45 - 3.5328 = 778.92
d. 63.258 + 734.2 = 797.5
Let the length of one be = x
Length of the other = 3x
Total length = 112 inches
x + 3x = 112
4x = 112
x = 112/4 = 28
x = 28 , 3x = 3*28 = 84
So the lengths are 28 and 84 inches.
Answer:
and 
Step-by-step explanation:
We have to write a multiplication equation and a subtraction equation that both involve a fraction and have the same solution.
Let the multiplication equation be,
.
And the subtraction equation is, 
Now,
and 
Therefore, in both the equations the solution is
