Chiếc xe tải cân nặng bao nhiêu tấn biết rằng khi chở 600kg gạo thì cả xe và gạo nặng 2 tấn Viết kết quả dưới dạng hỗn số A. 335 tấnB. 435 tấnC. 125 tấnD. 225 tấn
Chiếc xe tải cân nặng bao nhiêu tấn biết rằng khi chở 600kg gạo thì cả xe và gạo nặng 2 tấn (Viết kết quả dưới dạng hỗn số)
A. \(3\frac{3}{5}tấn\)B. \(4\frac{3}{5}tấn\)
C. \(1\frac{2}{5}tấn\)D. \(2\frac{2}{5}tấn\)
Trả lời:
Đổi đơn vị:
600Kg= \(\frac{3}{5}\)Tấn
=> Xe tải nặng: 2-\(\frac{3}{5}\)=\(\frac{7}{5}\)=(1\(\frac{2}{5}\))tấn (Chọn C)
1. Chiếc xe tải cân nặng bao nhiêu tấn biết rằng khi chở 600 kg gạo thì cả xe và gạo nặng 2 tấn ( viết kết quả dưới dạng hỗn số )
2. 2/5 của 10 a 20 m2 bằng bao nhiêu a
3. 6 m2 40 cm2 + 29990 cm2 = ....... m2 30 cm2
4. 15 Yến 9kg 1 + 6 Yến 15kg ( kết quả viết dưới dạng hỗn số )
5. Tìm x biết
( 3 và 3/5 -2): x = 2/5
1.Đổi 600 kg = \(\frac{3}{5}\)tấn .
Vậy chiếc xe tải nặng số kg là :
2 - \(\frac{3}{5}\)=\(\frac{7}{5}\)(tấn)
a) xe tải chở 30 bao gạo tẻ và 40 bao gạo nếp. mỗi bao gạo tẻ cân nặng 40kg.mỗi bao gạo nếp cân nặng 20kg. Hỏi xe đó chở bao nhiêu tấn gạo ?
Số gạo tẻ cân nặng :
30 x 40 = 1200 ( kg )
Số gạo nếp cân nặng :
40 x 20 = 800 ( kg )
Xe độ cho hàng nặng :
1200 + 800 = 2000 ( kg ) = 2 tấn
Đáp số : 2 tấn
Bài giải
Xe đó chở số ki lô gam gạo tẻ là : 30 x 40 = 1200 ( kg )
Xe đó chở số ki lô gam gạo nếp là : 20 x 40 = 800 ( kg )
Xe đó chở số tấn gạo là : 1200 + 800 = 2000 ( kg )
Đổi : 2000 kg = 2 tấn
Đáp số : 2 tấn
Số gạo tẻ cân nặng là:
40 x 30 = 1200 (kg)
Số gạo nếp cân nặng là:
20 x 40 = 800 (kg)
Xe đó chở số kg gạo là:
1200 + 800 = 2000 (kg)
Đổi 2000 kg = 2 tấn
Đáp số: 2 tấn
a) xe tải chở 30 bao gạo tẻ và 40 bao gạo nếp. mỗi bao gạo tẻ cân nặng 40kg.mỗi bao gạo nếp cân nặng 20kg. Hỏi xe đó chở bao nhiêu tấn gạo?
30 bao gạo tẻ cân nặng 30 x 40 =1200 (kg)
40 bao gạo nếp cân nặng 40 x 20 = 800 (kg)
Khối lượng gạo xe đó chở là 1200 + 800 = 2000 (kg)
Đổi 2000kg = 2 tấn
Bài giải
Khối lượng gạo tẻ xe đó chở được là :
40 x 30 = 1200 kg gạo = 1,2 tấn gạo
Khối lượng gạo nếp xe đó chở được là :
20 x 40 = 800 kg gạo = 0,8 tấn gạo
Khối lượng gạo xe đó chở được tất cả là :
1,2 + 0,8 = 2 tấn gạo
Đáp số: 2 tấn gạo.
Xe đó chở số kg gạo tẻ là:
30x40=1200 ( kg )
Xe đó chở số kg gạo nếp là:
40x20=800 ( kg )
Vậy xe đó chở số kg gạo là:
1200+800=2000 ( kg )
Đổi: 2000 kg = 2 tấn
Đáp số: 2 tấn
Một xe tải chở 30 bao gạo tẻ và 40 bao gạo nếp.Mỗi bao gạo tẻ cân nặng 40kg, mỗi bao gạo nếp cân nặng 20kg. Hỏi xe đó chở bao nhiêu tấn gạo
Khối lượng của 30 bao gạo tẻ là:
30 x 40 = 1200 ( kg )
Khối lượng của 40 bao gạo nếp là:
40 x 20 = 800 ( kg )
Đổi : 1200 kg = 1,2 tấn
800 kg = 0,8 tấn
Xe đó chở được số tấn gạo là:
1,2 + 0,8 = 2 ( tấn )
Đáp số : 2 tấn gạo
Xe đó chở \(30\times40+40\times20=1200+800=2000\left(kg.gạo\right)=2\left(tấn.gạo\right)\)
Cân nặng của 30 bao gạo tẻ:
\(30\times40=1200\left(kg\right)\)
Cân nặng của 40 bao gạo nếp:
\(40\times20=800\left(kg\right)\)
Số gạo xe đó chở:
\(1200+800=2000\left(kg\right)=2\left(tấn\right)\)
Bài 14: Một xe tải chở 30 bao gạo tẻ và 40 bao gạo nếp. Mỗi bao gạo tẻ cân nặng 40kg, mỗi bao gạo nếp cân nặng 20kg. Hỏi xe đó chở bao nhiêu tấn gạo?
Số gạo tẻ xe đó chở là:
40 x 30 = 1200 (kg)
Số gạo nếp xe đó chở là:
20 x 40 = 800 (kg)
Số gạo xe đó chở là:
1200 + 800 = 2000 (kg)
Đ/S: 2000 kg
Số kg gạo nếp là:
40 x 20 = 800 (kg)
Số kg gạo tẻ là :
30 x 40 = 1200 (kg)
Xe chở tổng số tấn gạo là:
1200 + 800 = 2000 (kg) = 2 (tấn)
Xe đó chở:
\(30\cdot40+40\cdot20=2000\left(kg\right)\)
Đổi 2000kg=2 tấn
