A : B = 5 : 2, Jika B = 4 Maka A= ...​

✘ Diketahui:

A : B = 5 : 2

B = 4

-----------------

✘ Ditanya:

A?

-----------------

✘ Jawab:

5 : 2

x : 4

x(÷2) : 4(÷2)

x : 2

------------------

x ÷ 2 = 5

x = 5 × 2

x = 10

------------------

✘ Pembuktian

10 : 4

10(÷2) : 4(÷2)

= 5 : 2

------------------

✘ Jadi

A = 10

A = 4 ÷ 2 × 5

A = 2 × 5

A = 10
