Question

Show work please :)
2. 1/9 x 3/4
4. 5/7 divided by 2/3
5. 7.89 - 3.9

Answer 1

As per questions,

2.

`(1)/(9) * (3)/(4)`

As 3 and 9 can be cancelled, we get,

`(1)/(3) * (1)/(4)`

Now multiplying denominators and numerators,

`(1)/(12)`

Hence, the required answer is
`(1)/(12)`

4.

`( (5)/(7) )/( (2)/(3) )`

When the base denominator (2/3) is reciprocaled,

`(5)/(7) * (3)/(2)`

As we can't directly divide, so we can multiply them,

`(5 * 3)/(7 * 2)`

`→ (15)/(14)`

Hence, the required answer is
`(15)/(14)`

5)

`7.89 - 3.9`

Direct subtraction, (Check solution in attached image)

`→3.99`
