（1-1/101）×（1-1/102）×(1-1/103)×…… ×(1-1/110)

(1-1/101）×（1-1/102）×(1-1/103)×…… ×(1-1/110)
=(101-1)/101×(102-1)/102×(103-1)/103×…… ×(110-1)/110
=100/101×101/102×102/103×…… ×109/110
=100/110
=10/11

How to calculate the process of 3 * (42-x) - 2x = 56

Check the math problem at 7:48, how many degrees is the angle between the hour hand and the minute hand, and how to calculate it?

Minute walk 360 / 60 = 6
360 / 12 = 30 per hour
48 minutes minute walk 48 * 6 = 288
7 hours, 30 * 7 = 210
48 minutes, 48 / 60 = 0.8
30*0.8=24
7: 48 is true, 210 + 24 = 234
288-234=54
At 7:48, the angle between the hour hand and the minute hand is 54 degrees

According to 21 times 37 equals 777, please choose the appropriate method to write the process of 74 times 84 times 125

74 by 84 by 125
=(2×37)×21×4×125
=(37×21)×2×4×125
=777×1000
=777000;
