1. Nửa lít=\(\frac{1}{2}l\)

Rót được số cốc là:

\(3\frac{1}{2}:\frac{1}{2}=7\)(cốc)

2. Để làm xong 1 chiếc bánh cần số kg là:

\(6:\frac{1}{3}=18\) (kg)

Cần thêm số kg để hoàn thành chiếc bánh là:

18-6=12 (kg)

\(x\times\frac{1}{2}+\frac{3}{2}\times x=\frac{4}{5}\)

  \(x\times\left(\frac{1}{2}+\frac{3}{2}\right)=\frac{4}{5}\)

                     \(x\times2=\frac{4}{5}\)

                             \(x=\frac{4}{5}\div2\)

                            \(x=\frac{4}{10}\)

\(=\frac{3}{5}.\frac{6}{5}.\frac{7}{6}.\frac{8}{7}+\frac{2}{5}+\frac{23}{35}\)

\(=\frac{24}{25}+\frac{2}{5}+\frac{23}{35}\)

\(=\frac{34}{25}+\frac{23}{35}=\frac{353}{175}.\)

a)  Số gạo ô tô đó chở là: 50 x 30 = 1 500(kg)

              1 500 kg = 1,5 tấn

Vậy ô tô đó chở 1,5 tấn gạo

b) nếu ô tô đó đã bớt hai phần năm số gạo đó thì số gạo còn lại là: \(1,5-\left(1,5\cdot\frac{2}{5}\right)=0,9\)(tấn)

             0,9 tấn = 9 tạ 

Vậy nếu ô tô đó đã bớt hai phần năm số gạo đó thì số gạo còn lại là 9 tạ

a, Ô tô chở được số gạo là :

30 x 50 = 1500 ( kg )

Đổi 1500 kg = 1,5 tấn

b, Nếu ô tô đó đã bớt \(\frac{2}{5}\)thì còn lại số phần số gạo là :

\(1-\frac{2}{5}=\frac{3}{5}\)

Số gạo còn lại là :

1,5 x \(\frac{3}{5}\) = 0,9 ( tấn )

Đổi 0,9 tấn = 9 tạ

Đáp số : a, 1,5 tấn

             b, 9 tạ

6+9543-655:5+44

=9549-131+44

=9418+44

=9462

969-2:17-2

=969-\(\frac{2}{17}\)-2

=\(\frac{16471}{17}\)-2

=\(\frac{16437}{17}\)

Spring is the beginning of a year. Around this time, the climate is still cold and humid. There are still some small drizzles outside but they seem not be able to stop the hundreds of colorful flowers blooming. Peach blossoms, apricot blossoms and lime trees are the most favorite plants for the Lunar New Year. Apricot blossom is yellow, peach blossom is pink, these color brighten up the sky. Spring arriving means that with New Year is coming. At this moment, everyone's heart is throbbing. The roads are filled with vehicles, everyone is happy, they go shopping to prepare for Tet holiday such as buying trees, clothes, foods.Traditionally, all of houses hang red sentences in front of the house, plant trees, wrap green cake to eat with melon onion. This is a characteris that only Vietnam has, leaves impression on the tourists. Children are especially happy to wear new clothes and receive red envelopes, are taken to visit the relatives. For me, the spring is so special, it carries so much love and happiness.
