Question

Help pls its 2 questions only the teacher didnt explain this

Answer 1

Explanation:

a) input is 2

2 * 3/4 = 6/4

(6/4) / (2/3) = 18/8 or 2.25

b) output is 1/2 (this time we go backwards)

if it is multiply we divide and if it is divide we multiply

1/2 * (2/3) = 2/6 (it said divide by 2/3 so we multiply)

(2/6) / (3/4) = 8/18 or 4/9 (it said multiply by 3/4 so we divide)

Answer 2

Explanation:

( a ). If input is 2

2 ×
`(3)/(4)` ÷
`(2)/(3)` =
`(3)/(2)` ×
`(3)/(2)` =
`(9)/(4)` = 2.25

If input is 2, then output is
`2(1)/(4)`

( b ). If output is 1/2

x ×
`(3)/(4)` ÷
`(2)/(3)` =
`(1)/(2)`

`(9)/(8)` x =
`(1)/(2)`

x =
`(1)/(2)` ÷
`(9)/(8)` =
`(4)/(9)`

If output is
`(1)/(2)` , then input is
`(4)/(9)`
