17. 4 1/2 - 2 2/3=

18. 7 - 3 1/3=

19. 14 3/4 - 1/6=

16. 40 7/5

17. 2 2/3

18. 6

19. 31/3

Step-by-step explanation:

Fraction math  or rationals.. okay

Step-by-step explanation:

the denominators need to be the same to add or subtract fractions... that is. the number in the bottom part of the fraction.

16)     17+23 + 4/5 +3/5  =  40+7/5   then reduce that improper fraction to 1 2/5

so your answer for  looks like 41 2/5

17)   4 1/2 - 2 2/3  get the denominators of the fractions the same first,  so  multiply (1/2 ) * 3 b/c it's the denominator of the other fraction.   so it's 3/6 now.. just another way to represent 1/2  = 3/6   then multiply (2/3 )*2 b/c it's the number in the denominator of the other fraction .. again.. so you have 4/6 =2/3 just another way to write that one too..   so then subtract 3/6-4/6 use that idea of taking one down from the upper digit.. so bring a 1 from the 4 which can be represented as 6/6  =1  add it to 3/6 +6/6  so you have 9/6-4/6=5/6  see?  4 is now 3 from the whole number  3-2=1 and 5/6 is the fraction so 1 5/6

18) 7 - 3 1/3   same idea bring down a whole 1 from the 7 and put it in the form of the other fractions denominator  so 3/3- 1/3 = 2/3   then 6-3 = 3  so you have 3 2/3

19) 14 3/4 - 1/6    just do the fractional part   3/4 - 1/6  ... get the denominators the same   (3/4 )*6= 18/24   and (1/6)4=4/24  then subtract 18/24-4/24=14/24 and put that fractional part with the whole number so you have 14 14/24 but usually we reduce a fraction if we can.. so  14 7/12  got it?
