1、

{961+(961÷ 2)+[(961÷ 2)+135.4]} ÷ 3 = 685.8 (tons)

2、

Cookies (44.2-24.3) ÷ (3-1) =10 (yuan)

Candy 44.2- 10×3= 14.2 (yuan)

3、

Half is1.5-1.05 = 0.45kg.

So honey is 0.45/ 1/2 = 0.9 kg.

Bottle1.5-0.9 = 0.6kg.

4、

12÷4=3 (yuan)

9÷4=2.25 (yuan)

2.25+3=5.25 (Yuan)

5、

69.4/2 = 347,000 Jin

(34.7-1.8)/2 =164500 kg

(34.7+1.8)/2182500 kg

34.7-18.25 =164500 kg

6、

Tonnage of a batch of goods per vehicle:1.5/(13-11) = 0.75.

Tonnage of the first vehicle: 0.75* 13=9.75.

Transport tonnage of the second vehicle: 0.75* 1 1=8.25.

7、

15 kg of flour is more expensive than 15 kg of rice: 0.14×15 = 2.1(Yuan).

Per kilogram of rice: (50.4-2.1) ÷ (20+15) =1.38 (yuan).

Per kilogram of flour:1.38+0.14 =1.52 (Yuan).

8、

The horizontal speed of the road is 20km/h,

The uphill speed is (20-2) ÷1.2 =15 (km/h).

Downhill speed: 15× 1.6 = 24 (km/h).

Take the flat road for one round trip: 40+40 = 80km,

Time: 80÷20 = 4 hours;

Uphill: 45+36 = 8 1 (km)

Time: 8 1÷ 15 = 5.4 (hours);

Downhill: 45+36 = 8 1 (km)

Time: 8124 = 3.375 (hours).

Round trip time: 4+5.4+3.375 = 12.775 (hours) ≈ 12.78 (hours).

9、

Seven days a week,

Four Mondays are 4*7=28 days.

There will be another Monday, neither the first day nor the last day.

So this month * * * has 28+3 =3 1 day.

The second and penultimate day is Monday.

So the first day is Sunday.

10、

Each box can hold: 300(2×2+6)= 30 pairs.

Each wooden case can hold 30×2=60 pairs.

Tip: Don't forget to write the answer!

Good luck with your study!
