Sân trường em có ba cây bàng mà các bạn trai gọi một cách hóm hỉnh là "cụ bàng". Gốc bàng to, thân cây gù, nổi thành nhiều bướu, mỗi bướu có hình thù khác nhau trông rất cổ quái. Mùa hè, tán bàng xanh biếc, bóng mát tòa rợp sân trường là nơi vui đùa của chúng em trong giờ ra chơi. Mùa thu, lá bàng đỏ ối như những chiếc quạt lụa óng a óng ánh tuyệt đẹp. Cây bàng là vương quốc của đàn chim sâu, còn đối với chúng em, nó là người bạn thương yêu của tuổi thơ.

Bác Tư mua 2 bóng đèn và 4 mét dây điện hết 17000 đồng
Vậy giá của 4 bóng đèn và 8 mét dây điện sẽ là 34000 đồng
Bác Ba mua 4 bóng đèn và 3 mét dây điện hết 17000 đồng
nên giá của 8 - 3 = 5 mét dây điện sẽ là 34000 - 17000 = 17000 đồng
Vậy giá của 1 mét dây điện là: 17000 : 5 = 3400 đồng
giá của 3m dây điện là: 3400 x 3 = 10200 đồng
suy ra, giá của 1 bóng đèn là: 17000 - 10200 =6800 đồng
số bé nhất có ba chữ số là: 100
ta coi số cần tìm là x:
x:5-35=100
x:5 =100-35
x:5 =65
x =65:5
x = 13
vậy số cần tìm là 13
