Math ? Huh?
In the first video the man baked 28 donuts and he has to split them up between 7 people. The man is saying that they each get 13 donuts. He is saying that 28/7 is 13. He said 7 does not go into 2 but it goes into 8, 1 time, and since you didn’t use the 2, he brought it back and said 7 goes into 21 3 times, so he says its 13. Each person should get 4 donuts because 21/4 equals 7.
In the second video the man was splitting up 25 % of his parent’s fortune between 5 people. The parents thought it was 14% the parents said 14x5 is 25.
He did 4x5 and 1x5 and he got 25 because 4x5 is 20 and 1x5 is 5. It should be 5%.
