Question

Nine tenths minus one third

Answer 1

First find the GCF of 10 and 3 --> 30


`(9)/(10)` x
`(3)/(3)` =
`(27)/(30)`


`(1)/(3)` x
`(10)/(10)` =
`(10)/(30)`

Now subract
`(27)/(30) - (10)/(30)`

Answer =
`(17)/(30)`

Reduce if possible -- cant reduce further..

answer 17/30

Answer 2

`(9)/(10) - (1)/(3) \\ (9(3))/(10(3))- (1(10))/(3(10)) \\ (27)/(30)- (10)/(30) \\ (17)/(30)`
