Three quarters = () divided by 16 = half: ()

Three quarters = () divided by 16 = half: ()

Three quarters = 12 divided by 16 = half: two thirds

Simple calculation of 42 times (1 / 6 + 1 / 7)

42 times (1 / 6 + 1 / 7)
=42x1/6+42x1/7
=7+6
=13

Step by step calculation: x + 50% x = 8.5 (1-75%) x = 42 20-20% x = 3.6 30% x + 15% x = 27

（1） x+50%x=8.5
（1+50%）x=8.5
x=17/3
（2）（1-75%）x=42
25%x=42
x = 168
（3） 20-20%x=3.6
20%x=20-3.6
0.2x=16.4
x=82
（4）30%x＋15%x=27
45%x = 27
x=60

(75% x-56) △ x = 2 △ 2 + 3) write the calculation process

（75%x-56）÷x=2÷（2+3）
(0.75x-56)÷x=0.4
0.75x-56=0.4x
0.75x-0.4x=56
0.35x=56
x=160

Simple algorithm of 2.73 * 1.67-0.96 * 0.75

2.73*1.67-0.96*0.75
=2.73*(2-0.33)-0.96*3/4
=2.73*2-2.73*0.33-0.24*3
=5.46-0.9009-0.72
=5.46-0.72-(1-0.0991)
=4.74-1+0.0991
=3.74-0.0991
=3.6409
