Question

explain it why it happens​

Answer 1

$\large{\boxed{\bf{AnswEr}}}$

• P/q form of 4.7(bar over 7) is 43/90

__________________________

Given :-

• 0.47(bar over 7)

To Find :-

• P/q form of this

__________________________

$\large{\boxed{\bf{Solution}}}$

• Let 0.47(bar over 7) be x

Then,

➪ x = 0.47777...........

• Multiply both sides by 10

Then,

➪ 10x = 4.7777...........1]

• Multiply both sides by 100

Then,

➪ 100x = 47.7777..........2]

★ Subtract equation 1] from equation 2].

Then,

︎︎︎ 100x - 10x = 47 - 4

➪ 90x = 47 - 4

➪ 90x = 43

➪ x = 43/90

Hence, the p/q form of 0.47(bar over 7) is 43/90.
