Grade 5 1/2*4/9=2/9 Grade 6 1/2*4/5=2/5 Grade 6 completed more tasks.
3 (26-2)/( 1- 1/5*2)=40
4 40/ 1 1/ 15-( 1-3/5)= 120
5 34/( 1/30- 1/540)= 1080
6 (26-8)/82/ 1
7 5/( 1/3-7/24)= 120
8 ( 12/6)/60= 1/ 10
9 30/2*3/(3+2)=9 9*2/3=6
10 1/( 1/ 10- 1/ 15)=30 30- 15= 15()
1. use x meters.
3/5X+0.5= 18.5
3/5X= 18
x=30
2.4/9=20/45
4/5=36/45
20/45 is less than 36/45
So I finished reading a little more in the sixth grade.
The fifth grade completes 2/9 of the whole grade, and the sixth grade completes 2/5 of the whole grade.
3. Set the original X kilograms of oil.
1/5x + 1/5x-2=x-26
2/5x-2=x-26
-3/5 times =-24
x=40
4. Set the original X bucket
x-3/5x+40 = 1 1/ 15x
2/5x+40 = 1 1/ 15x
6/ 15x+40 = 1 1/ 15x
5/ 15x =40
x= 120
5. Suppose you withdraw X yuan.
1/30x- 1/540x=34
18/540x- 1/540x=34
17/540x=34
x= 1080
6.(26-8)/8=2.25=225%=4/9
7. Because intermediate books have not changed, intermediate books account for all 1/3.
Then the lower level is 1-7/24- 1/3=9/24.
9/24-7/24=5×2
1/ 12=5×2
A * * *10 ÷112 =120 (Ben)
8. 12 ÷2=6 (kg)
6÷60 =0. 1= 1/ 10
The answer is110.
9. If the length is x cm, the width is 2/3x.
(x+2/3X)×2=30
X=9
9×2/3=6 cm
6×9=54 (square centimeter)
10. 1-( 1/ 15× 10 )= 1/3
1/3÷ 10= 1/30
So b will take 30 days to complete.
