anh em giúp tôi câu này với

20 tháng 7

Giải:

Theo bài ra ta có sơ đồ:

Theo sơ đồ ta có:

Chiều dài mảnh đất là: 12: (3 - 2) x 3 = 36(m)

Chiều rộng mảnh đất là: 36 - 12 = 24(m)

Diện tích mảnh đất là: 36 x 24 = 864(m\(^2\))

Đáp số: 864m\(^2\)

Ta có: 100 000 000 = 99 999 999 + 1

Mà 99 999 999 ⋮ 3 và 1 chia dư 1

⇒ (99 999 999 + 1) chia 3 dư 1

⇒ 100 000 000 chia 3 dư 1

20 tháng 7

Tổng các chữ số của số 100000000 là:

1 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 = 1

Vì 1 : 3 dư 1 nên :

100000000 : 3 dư 1

Ta có: \(7,32\times33+7,32\times67\)

\(=7,32\times\left(33+67\right)\)

\(=7,32\times100=732\)

20 tháng 7

7,32 x 33 + 7,32 x 67

= 7,32 x (33 +67)

= 7,32 x 100

= 732

123 x 123 x 44133

= 15129 x 44133

= 667688157

3 lần số lớn là:

21,65 - 3,65 = 18

Số lớn là:

18 : 3 = 6

Số bé là:

6 - 3,65 = 2,35

Tích của hai số là: .

6 x 2,35 = 14,1

Đáp số: 14,1

@ Kẻ Mạo Danh. 3 lần số lớn em lấy đâu ra, đề bài chưa cho, em cần giải thích rõ cho tài khoản vip Olm.

4 lần số lớn hơn số lớn là:

4 - 1 = 3 (lần số lớn)
