If it takes eight men ten hours, it would take seven men nine hours, six men eight hours, five men seven hours and that brings us to the answer you need. It would take four men six hours.
I think the answer might be x=4/8
ANSWER:
It is true as the divisibility rule of three says -
WE HAVE TO ADD ALL THE DIGITS OF THE NUMBER AND IF THAT SUM IS DIVISIBLE BY THREE THEN THE PARTICULAR NUMBER IS DIVISIBLE BY THREE.
EXAMPLE 2+7=9 and 3*3=9
HOPE IT HELPS!!!!
PLEASE MARK BRAINLIEST!!!!
3/5 + 7/10 / 7/12 - 3/10
13/10 / (35/60 - 18/60=)17/60
10/13 x 60/17 = 78/17 = 4 10/17
