Question

2p/21 + 5/7= 4/3

Pls explain ​

Answer 1

Answer:

13/2

Step-by-step explanation:

2p/21+5/7=4/3

or, 2p/21= 4/3-5/7 [ transposing]

or, 2p/21=28-15 /21 [ LCM of denominators divided by the denominators of the fraction then the result is multiplied with numerator]

or, 2p/21= 13/21

or, 2p×21=13×21 [cross multiplication ]

or, 42p=273

or, p= 273/42 [transposition law]

or, p= 13/2 [cancellation ]

Transposition law means changing the side of the numbers or fractions
