Bài 1: Tính
3/5 + 4/3 x 5/6 2 - 7/6 + 1/3 7/6 x 3 - 3/5
giúp mình với, trả lời mình tick cho
tính
3/4x5/7 5/8x4/15 7/12x4/9 1/6x3/5 12/21x23/8 13/4x5/39 7/42x13/21 3/16x4/15
ai e tick cho
\(\dfrac{3}{5}\) x \(x\) \(-\) \(\dfrac{3}{2}\) = \(\dfrac{5}{6}\)
\(\dfrac{12}{15}+\dfrac{37}{7}+\dfrac{16}{5}+57\)
rút gọn rồi tính
3 phần 6 cộng 12 phần 8 , 2 phần 5 cộng 56 phần 40 ,4 phần 6 cộng 16 phần 24
5/6 + 5/8 + 3/4
12/15 + 3 + 3/5
4/3 x 7/8 x 5
8/9 x 6/5 : 3
7/12 + 5/8 x 4/3 - 3/4
(8/5 - 7/6) : 13/15 + 1/4
Tính nhanh:
a, 5/6 x 4/5 + 4/5 x 1/6 + 4/5
b, 60 x (7/12 + 4/15)
Xin lời giải chi tiết ạ
Tính nhanh
a,(1+2 +3 +...+99) x (13 x 15 – 12 x 15 –15)
b,2+4+ 6+...+ 98+100–(1+3 +5 +...+97+99)
tính
3/4+1/4x2/5-1/2
