Question

Help me out ? 10-12

Answer 1

10. 1

11. 1 21⁄25

12. 1 1⁄24

Explanation:

`12. \: ((4 / 2)/(3) ) + ( ( (3)/(2) )/(4)) = (2)/(3) + (3)/(8) = (16)/(24) + (9)/(24) = (25)/(24) = 1 (1)/(24)`

`11. \: ( (4)/(5) )^(2) + 2( (3)/(5) ) = (16)/(25) + (6)/(5) = (16)/(25) + (30)/(25) = (46)/(25) = 1 (21)/(25)`

`10. \: (3(2)(3) - 4)/(7(2)) = (18 - 4)/(14) = (14)/(14) = 1`

I am joyous to assist you anytime.
