Xiao Gang is very careless. When he calculates a division problem, he regards dividing by 3 / 7 as multiplying by 3 / 7, and the result is 5 / 28. What is the correct result of this problem?
Xiao Gang in the problem, due to carelessness, mistakenly divided a number by 8 as a multiplication of 8, the result is 24 / 45, do you know the correct answer
Let that number be X
therefore
X*8=24/45
So x = 3 / 45 = 1 / 15
So the right answer
1/15÷8=1/120
