The problem of grade six score calculation can be simplified as 4/9× 5×18 = 4/9×18× 5 = 40. Use exchange method, correlation method and distribution rate.

It's just a simple math problem in sixth grade. If it can be simplified, simplify the original formula =(3/8+4/8)x5/4.

= 7/8×5/4

=35/32

= 1 3/32

The sixth grade calculation problem ... should be simplified if it can be simplified. (There must be a process) = (157-1) ×157157-15665438.
