Solution: 0.6x=4.8
x=4.8÷0.6
x=8
1.4:x= 1:0.75
Solution: x= 1.4×0.75.
x= 1.05
50.4X2.7+24.48÷24
=(50+0.4)×2.7+(24+0.48)÷24
=50×2.7+0.4×2.7+24÷24+0.48÷24
= 135+ 1.08+ 1+0.02
=( 135+ 1)+( 1.08+0.02)
= 136+ 1. 1
= 137. 1

(2-3/32+3/4)÷ 1/4
=(2-3/32+3/4)×4
=2×4-3/32×4+3/4×4
=8- 1/8+3
= 1 1- 1/8
= 10 7/8
[4-(0.5+2)]X0.75
=[2-0.5]×3/4
=2×3/4- 1/2×3/4
