Question

Simplify [(7/9 )7 ×(7/9)3 ] ÷ [(7/9 )5 ×(7/9)2 ]

Answer 1

Answer:

3/2

Step-by-step explanation:

= [(49/90)into 7/9] divided by [(49/9) into (14/9)]

= [(343/81) into 3] divided by(683/81)

(343/27) divided by (683/81)

so (683/81) will be reciprocated.

(343/27) into (81/683)

we will do the cancellation.

343 will be cancelled will 683

= 343(1) and 683(2)

= 27 and 81 will cancelled.

=27(1) and 81(3)

= THEREFORE. THE ANSWER IS 3/2

pls mark me as brainliest.
