Ta có:
\(\frac{A}{B}\)= \(\frac{3}{4}\)= \(A\) \(:\) \(B\) = \(3\) \(:\) \(4\)
\(A\): \(2\)= \(\frac{3}{2}\)= \(1,5\)
\(B\) x \(2\)= \(4\) x \(2\)= \(8\)
Ta có tỉ số mới là:
\(1,5\) \(:\) \(8\)= \(\frac{1,5}{8}\)= \(\frac{15}{80}\)= \(\frac{15:5}{80:5}\)= \(\frac{3}{16}\)
Vậy ta có tỉ số mới là: \(\frac{3}{16}\)

Ta cưa được số khúc gỗ là:
80 : 16 = 5 (khúc)
5 khúc gỗ cưa thành 4 lần cưa và nghỉ 4 lần.
Bác thợ mộc cưa xong cây gỗ hết số phút là:
( 5 + 3 ) x 4 = 32 (phút)
Trả lời ;
Ta sẽ cưa cây gỗ thành 5 khúc, như vậy có tất cả 4 lần cưa.
Mỗi lần cưa hết 5 phút và bác nghỉ thêm 3 phút, như vậy tổng số thời gian 1 lần cưa là 8 phút.
Vậy thời gian bác cưa hết cây gỗ là:
8 x 4 = 32 (phút).
Trong lời giải của bạn Duyên, phải trừ đi 3 phút lần nghỉ cuối cùng không tính. Vậy Bác thợ mộc cưa hết cây gỗ trong:
32 - 3 = 29 (phút.)
Đáp số: 29 phút.
Giải :
Hiệu giữa chúng là:
20 x 2 = 40
Số lớn là:
(338 + 40) : 2 = 189
Số bé là:
189 – 40 = 149
Giải
Hiệu giữa chúng là: 20 x 2 = 40
Số lớn là: (338 + 40) : 2 = 189
Số bé là: 189 – 40 = 149
Cửa hàng bán xe đạp điện đó giảm giá số tiền là:
11 000 000 : 100 x 20 = 2 200 000 (đồng)
Giá 1 chiếc xe đạp điện đó là:
11 000 000 - 2 200 000 = 8 800 000 (đồng)
Đáp số: 8 800 000 đồng.
Giá bán chiếc xe đạp chiếm:
100% - 20% = 80% ( giá bán ban đầu )
Giá của 1 chiếc xe đạp lúc này là:
11 000 000 : 100 x 80 = 8 800 000 ( đồng )
