[(8.4一7.9)÷0.25]x1.2的递等式计算

Answer 1

[(8.4一7.9)÷0.25]x1.2的递等式计算

[(8.4一7.9)÷0.25]x1.2
=[0.5÷0.25]×1.2
=2×1.2
=2.4

〔(8.4—7.9)÷0.25〕×1.2用递等式

〔(8.4—7.9)÷0.25〕×1.2
=〔0.5÷0.25〕×1.2
=2×1.2
=2.4.

递等式计算 1.25x0.25x16 3.75÷0.125-2.75

1.25×0.25×16
＝1.25×0.28×（4×4）
＝（1.25×4）×（0.25×4）
＝5×1
＝5
3.75÷0.125-2.75
＝3.75÷（1÷8)-2.75
＝3.75×8-2.75
＝29-2.75
＝26.25

递等式计算 （3.6+8.4）÷0.25 2.3x8.37+16.3x2.3

（3.6+8.4）÷0.25
=12÷0.25
=48
2.3x8.37+16.3x2.3
=19.251+37.49
=56.741

递等式计算。103x0.25 2.5x102 4.8x0.25

103x0.25 +2.5x10.2 4.8x2.5
=0.25*103+0.25*102+0.25*48
=0.25*（103+102+48）
=0.25*253
=63.25

1.01×7.9的启递等式计算

1.01×7.9的递等式计算：
1.01×7.9
＝(1+0.01)x7.9
=7.9+0.079
=7.979

96x0.125x0.25x0.5递等式计算

等于8×3×4×0.125×0.25×0.5=8×0.125×4×0.25×3×0.5=1×1×3×0.5=1.5

递等式计算16.4 ÷0.25

递等式计算
16.4÷0.25
=16.4x4
=65.6

9.25÷0.25递等式计算

9.25÷0.25递等式计算
9.25÷0.25
=（9+0.25）÷0.25
=9÷0.25+0.25÷0.25
=36+1
=37

递等式计算 0.4x0.93x0.25x10 0.65x99

递等式计算
0.4x0.93x0.25x10
=（0.93×10）×（0.4×0.25）
=9.3×0.1
=0.93
0.65x99
=0.65×（100-1）
=0.65×100-0.65
=65-0.65
=64.35
