Instead of just giving you the answer, I will do steps.
First:
Let "x" be the number
Therefore,
2x = 78.
x = 78/2
x = 39
The number is 39
6 times 13 equals 78 3 times 26 equals 78 2 times 39 equals 78 and 1 times 78 equals 78
2 x 39 equals 78
78.
It is: 6 times 13 = 78
9.75 times 8 equals 78.
It is: 78 times 3,237 = 252,486
78 x 5 = 390
26
How about 6 times 13 = 78 as one example
78 divided by 8 (or 78/8) equals 9.75.
19.5
just do 78/54 which equals 1.44
