Step-by-step explanation:

sorryy if they are wrong

(1) 27/100 (2) 17 3/20

Step-by-step explanation:

(1)

27 /8  ÷ 25 /2

=   27 /8  ×  2 /25

=   27 × 2 /8 × 25

=   54 /200

=   54 ÷ 2 /200 ÷ 2

=   27 /100

(2)

67 /4  + 2 /5

=   67 × 5 /4 × 5  +  2 × 4 /5 × 4

=   335 /20  + 8 /20

=   335 + 8 /20

=   343 20  = 17 3 /20

Tip!

Fraction Calculator is very helpful and I suggest (if you actually want to do the math) that every time you see a fraction you should divide top by bottom then multiply it by 100 to get a whole number then just simplify it and convert it back into a fraction :)
