解:4.8÷0.16÷0.3等于( 100 )
∵已知需求出4.8÷0.16÷0.3等于多少
X ÷ Y = X / Y = Z
∴4.8 ÷ 0.16 ÷ 0.3
= (4×10+8)/10 ÷ 16/100 ÷ 3/10
= 48/10 ÷ 4/25 × 10/3
= 24/5 × 25/4 × 10/3
= 24/5 × (25/4 × 10/3)
= 24/5 × 125/6
= 100
答:4.8÷0.16÷0.3等于100
4.8÷1.6÷0.3
解:=4.8÷(1.6×0.3)
=4.8÷0.48
=10
1.6*3/0.16/0.3
=1.6/0.16*3/0.3
=10*10
=100
=30除3.3=9.09090909091
