Question

a. x/15=4/3

b. x: 4/3 =5/6

c. 7/2 - x =5/6

  giải giúp mik nhanh vs ạ :-(

Answer 1

a. x/15 = 4/3

x = 4/3 . 15

x = 20

b. x : 4/3 = 5/6

x = 5/6 . 4/3

x = 10/9

c. 7/2 - x = 5/6

-x = 5/6 - 7/2

-x = 8/3

Answer 2

a. \(\dfrac{x}{15}=\dfrac{4}{3}\)

=> 3x = 15 . 4 

=> 3x = 60

=> x = 20

b. x : \(\dfrac{4}{3}=\dfrac{5}{6}\)

=> x = \(\dfrac{5}{6}\) . \(\dfrac{4}{3}\)

=> x = \(\dfrac{10}{9}\)

c. => x = \(\dfrac{7}{2}-\dfrac{5}{6}=\dfrac{21}{6}-\dfrac{5}{6}=\dfrac{16}{6}=\dfrac{8}{3}\)

=> x = \(\dfrac{8}{3}\)

Answer 3

a,x/15=4/3<=>x=20/15  b,5/6.4/3<=>x=20/18   c,7/2-5/6<=>x=8/3

chuc ban hoc tot.
