The construction site uses three - thirds of the cement in two days, and two - thirds of the cement in the second How many tons of cement are used in two days

The construction site uses three - thirds of the cement in two days, and two - thirds of the cement in the second How many tons of cement are used in two days

2/3:(1+3/2)
=2/3×2/5
=4 / 15 (ton)
4 / 15 × 3 / 2 = 2 / 5 (ton)
A: 4 / 15 tons on the first day and 2 / 5 tons on the second day
I checked it out. It's right
But I started with equations
Suppose x tons are used in the first day, then 3 / 2x tons are used in the second day
X+3/2X=2/3
I don't know if you can understand it
