The calculation should be simple. (44.6-42.8) / (3.62 + 2.38) 4.8 * 9.9 + 0.48

The calculation should be simple. (44.6-42.8) / (3.62 + 2.38) 4.8 * 9.9 + 0.48

（44.6-42.8）÷（3.62+2.38）
=1.8÷6
=0.3
4.8*9.9+0.48
=4.8*9.9+4.8*0.1
=4.8*（9.9+0.1）
=4.8*10
=48

How is 2.38 * 3.6 + 5.4 * 2.38 + 2.38 easy to operate

2.38*3.6+5.4*2.38+2.38
＝2.38x(3.6+5.4+1)
=2.38x10
=23.8

765×213×1/27＋765×327×1/27

765×213×1/27＋765×327×1/27
=765×1/27×（213+327）
=765×1/27×540
=765×20
=1530

765 * 213 / 27 + 765 * 327 / 27 =?, it's better to have ideas and steps to solve the problem!

Because both numbers have a factor of 765 / 27, we have to extract them
765/27*（213+327）
=765/27*540
=765*20=15300

Question 1: (101 + 103 + ＋199)-(90＋92＋… Second question: 765 × 213 △ 27 + 765 × 327 △ 27
Question 3: 9 × 17 + 91 △ 17-5 × 17 + 45 △ 17. Question 4: (9999 + 9997 + ＋9001)-(1＋3＋… (873 × 477-198) / (476 × 874 + 199)

The first question: equivalent to 11 × 50. The answer is 550. The second question: equivalent to 765 × 540 △ 27, that is 765 × 20. The answer is 15300. The third question: can be reduced to 12 × 17 + 136 △ 17, the answer is 212. The fourth question: equivalent to 9000 × 5000, the answer is 45000000

Simple operation of 0.04 times 1.38 times 25 divided by 0.46

=0.04*25*(1.38/0.46)=1*3=3

How to calculate 0.04 times 1.38 times 25 and 0.46

0.04*1.38*25/0.46
=(0.04*25)*(1.38/0.46)
=1*3
=3

Simple calculation: 5 / (8 / 11) / (11 / 13) / (13 / 24)

To divide by a fraction is to multiply by its reciprocal
Original formula = 5 x (11 / 8) x (13 / 11) / (24 / 13)
= 5 X （24/8）
=5 x 3
= 15
I'm very glad that the team will answer for you

Simple calculation of 11 / 10 * 24 * 25 / 33

11 out of 10 * 24 * 33 out of 25
=12/5*33/25
=396/125
=3 and 21 / 125

10 + 11 + 12 + 13 + 14 = several times several 23 + 24 + 25 + 26 + 27 = several times several 210 + 220 + 230 + 240 + 250 = several times several

10 + 11 + 12 + 13 + 14 = 12 times 5
23 + 24 + 25 + 26 + 27 = 25 times 5
210 + 220 + 230 + 240 + 250 = 230 times 5
