936/ 12*6=936*6/ 12
6/ 12=0.5= 1/2
So 936/12 * 6 = 936 *1/2 = 936 * 0.5 = 468.
It is a simple calculation law, which is involved in the second volume of the fourth grade mathematics textbook of the People's Education Press: in the multiplication operation of two numbers, according to the calculation order from left to right, the two factors are multiplied, and the position of the exchange factor remains unchanged. Specifically, when two numbers are multiplied, the positions of exchange factors and their products remain unchanged. It's called multiplicative commutative law.
