15/24=x/56

x/56=15/24

x/56=0.625

x=0.625*56

x=35

Answer 2

=> 15*56=24*x
840=24*x
x=840:24
x=35

Answer 3

15/24 = x/56

=> 5/8 = x/56

=> 5/8 = 35/56

k cho mk nhe bn

Answer 4

\(\frac{15}{24}=\frac{x}{56}\)

\(\Rightarrow15.56=24x\)

\(\Rightarrow840=24x\)

\(\Rightarrow x=840:24\)

\(\Rightarrow x=35\)

Vậy x = 35

Answer 5

giản ước 15 / 24 = 5 / 8

=> x = 56 : 8 x 5 = 35 ( quy đồng phân số 5 / 8 = x / 56 )
