Question

2/3+1/4-3/5 =

2/3-1/4+3/5 =

Nhanh thì mình k cho

Answer 1

2/3+1/4-3/5 =19/60

2/3-1/4+3/5 =61/60

Answer 2

2/3 + 1/4 - 3/5 = 11/12 - 3/5  =19/60

2/3 - 1/4 + 3/5 = 5/12 + 3/5 = 61/60 

k cho mk nha!

Answer 3

\(\frac{2}{3}+\frac{1}{4}-\frac{3}{5}=\frac{19}{60}\)

\(\frac{2}{3}-\frac{1}{4}+\frac{3}{5}=\frac{61}{60}\)

Answer 4

2/3 + 1/4 - 3/5

= 8/12 + 3/12 - 3/5

= 11/12 - 3/5

= 55/60 - 36/60

= 19/60

2/3 - 1/4 + 3/5 

= 8/12 - 3/12 + 3/5

= 5/12 + 3/5

= 25/60 + 36/60

= 61/60

Answer 5

Cám ơn đã giúp mình

Answer 6

không có gì

Answer 7

\(\frac{2}{3}+\frac{1}{4}-\frac{3}{5}\)

\(=\frac{40}{60}+\frac{15}{60}-\frac{36}{60}\)

\(=\frac{19}{60}\)

_____________________________

\(\frac{2}{3}-\frac{1}{4}+\frac{3}{5}\)

\(=\frac{40}{60}-\frac{15}{60}+\frac{36}{60}\)

\(=\frac{61}{60}\)
