Question

Calcule o coeficiente:

a) 2a/b : x/y =

b) 3x/4 : 5y/7=

c) x/2 : ax/8 =

d) 5x/a : a/xy =

Answer 1

a) 2a/b : x/y =

= 2a/b.(y/x)

= 2ay/bx

coeficiente : 2

b) 3x/4 : 5y/7=

= 3x/4.(7/5y)

= 21x/20y

21/20 (coeficiente )

c) x/2 : ax/8 =

x/2.(8/ax)

= 8x/2ax

4 (coeficiente)

d) 5x/a : a/xy =

5x/a. (xy/a)

= 5x²y/a2

= 5 (coeficiente )
