Here, the number is = 9/15/18
We can re-write it as: 9 /15*18 = 9/270 = 1/30
In short, Your Answer would be 1/30
Hope this helps!
So first you would plug 3 into the x values in the equation. (3)+1/2+15-1/2. EVALUATE AND THE ANSWER IS 18!!
No it is not because 15 out of 30 is half but 12 out of 20 is more than half
Answer:
5 bags of cement are required.
Step-by-step explanation:
Since to make concrete, the ratio of cement to sand is 1: 3, if cement and sand are sold in bags of equal mass, to determine how many bags of cement are required to make concrete using 15 bags of sand the following calculation must be done:
Cement = 1
Sand = 3
3 = 15
1 = X
15/3 = X
5 = X
Therefore, 5 bags of cement are required.
