Ask some simple mathematical problems (2 / 3 + 1 / 6) * 6 / 11 / 9 * 14 / 5 * 22 / 65 * 11 / 4 + 11 / 4 4 / 5 * 1 / 4 * 5 / 6 (28 + 4 / 5) * 5 / 7 (2 / 3-1 / 2) * 3 / 4 These six questions can be calculated simply, they must be calculated simply

Ask some simple mathematical problems (2 / 3 + 1 / 6) * 6 / 11 / 9 * 14 / 5 * 22 / 65 * 11 / 4 + 11 / 4 4 / 5 * 1 / 4 * 5 / 6 (28 + 4 / 5) * 5 / 7 (2 / 3-1 / 2) * 3 / 4 These six questions can be calculated simply, they must be calculated simply

The first one is the original formula of factorization = 2 / 3 * 6 + 1 / 6 * 6 = 5, the second one is the original formula = (9 / 11 * 22) * 5 / 14 = 45 / 7 = 45 / 7, the third one is the original formula of extraction of common factor = (65 + 1) * 4 / 11 = 24, the fourth one is the original formula = (4 / 5 * 5 / 6) * 1 / 4 = 1 / 6 = 1 / 6, the fifth one is the original formula of factorization = 28 * 5 / 7 + 4

(9 / 16 + 9 / 32 minus 3 / 8) times 3 / 4
11 / 15 divided by 7 + 1 / 7 multiplied by 4 / 15
One fifth multiplied by one sixth divided by one fifth into one sixth
(four fifths to one third) divided by two fifths
Seven eighths + one eighth by four fifths
Two fifths multiplied by 101 minus two fifths
One seventh + one seventh divided by one seventh + one seventh
Five out of seven minus five out of seven times one in half

1.（9/16+9/32-3/8）*3/4=（27/32-12/32）*3/4=15/32*3/4=45/128
2.11/15÷7+1/7*4/15=1/7*（11/15+4/15）=1/7
3.1/5*1/6÷1/5*1/6=1/6*1/6=1/36
4.（4/5-1/3）÷2/15=4/5*15/2-1/3*15/2=6-5/2=7/2
5.7/8+1/8*4/5=1/8*（7+4/5）=1/8*39/5=39/40
6.2/5*101-2/5=2/5*（101-1）=2/5*100=40
7.1/7+1/7÷1/7+1/7=1/7+1+1/7=9/7
8.5/7-5/7*1/2=5/7*（1-1/2）=5/7*1/2=5/14

567 × 235-267 / 300 + 567 × 234

(267＋567×234)/ (567×235－300)
=(267+300＋567×234-300)/ (567×235－300)
=(567＋567×234-300)/ (567×235－300)
=(567×235-300)/ (567×235－300)
=1
