THẾ SỐ THÔI BẠN

0.3 + 0.3 : 0.25 + 0.3 : 0.5 + 0.3 : 0.125=700.9875

k nha!

mình nhanh nhất!

    0.3 + 0.3 : 0.25 + 0.3 : 0.5 + 0.3 : 0.125 

= 0.3 : 1 + 0.3 : 0.25 + 0.3 : 0.5 + 0.3 : 0.125

= 0.3 : ( 1 + 0.25 + 0.5 +0.125 )

= 0.3 : 1.875

= 0.16

Câu Trả Lời : Tự Làm đi

x=(6và3/5-0.125*8+2vvà 2/15*0.03)*25/3

X=(33/5-1+32/15*3/100)*25/3

x=(28/5+8/125)*25/3

=708/125*25/3

=236/5

Câu a:

(4 5/37 - 3 4/5 + 8 15/29) - (3 5/37 - 6 14/29)

= (4 5/37 - 3 5/37) + (8 15/29 + 6 14/29) - 3 4/5

= 1 + 15 - 3 4/5

= 16 - 3 - 4/5

= 13 - 4/5

= 61/5

Câu b:

(2\(\frac56\) + 1\(\frac49\)) : (10\(\frac{1}{12}\) - 9\(\frac12\))

= (17/6 + 13/9) :(121/12 - 19/2)

= (51/18 + 26/18) :(121/12 - 114/2)

= 77/18 : 7/12

= 77/18 x 12/7

= 22/3
