Một cạnh của hình vuông là:
\(\dfrac{15}{7}\):4 = \(\dfrac{15}{28}\)(m)
Diện Tích là:
\(\dfrac{15}{28}\)x\(\dfrac{15}{28}\)=...(m2)
Đáp số .... m2
Còn lại em tự làm nhé

chị làm nhé

Đổi 4m=40dm
Diện tích hình thoi là:
40×152=300(dm2)

dễ mà phần bù là phần cộng thêm vào cho nó thành số tự nhiên
VD: \(\dfrac{98}{103}\) + \(\dfrac{5}{103}\) = 1
\(\dfrac{94}{99}\) + \(\dfrac{5}{103}\) = 1
Phần bù nào càng bé thì càng lớn end♫

cùng mẫu số nên ko cần quy đồng nhé♪♪≈
\(\dfrac{7}{10}\)+\(\dfrac{4}{10}\) = \(\dfrac{11}{10}\)
