Step 4 solve the problem

1.90 = 1 time; 90 = 2 times; 45 = 3 times; 30 = 5 times; 18 = 6 times; 15 = 9 times; There are six kinds of 10, namely 1 and 90, 2 and 45, 3 and 30, 5 and 18, 6 and 15, 9 and 10.

2.336 = 2 times; 2 times; 2 times; 2 times; 3 times; 7 = 6 times; 7 times; eight

6+7+8=2 1

3.( 1)260 = 2 times; 2 times; 5 times; 13 so these two numbers are 4 and 65.

(2)420 = 2 times; 2 times; 3 times; 5 times; 7 So these two numbers are 4 and 105, 12 and 35, 15 and 28, 20 and 2 1.

leave out

6.( 1)48 = 2 times; 2 times; 2 times; 2 times; 3 So A=3 and B= 12.

(2) Omission

7. (1)16 = 3+13 = 5+11= 7+9, so there are six such simplest scores.
