Answer:
Step-by-step explanation:
3rd one
Answer:
-3 5/12=k
Step-by-step explanation:
K+5/3= -7/4
subtract 5/3 from both sides
K= -7/4-5/3
lcm of 4 and 3 is 12
so
K= -21/12-20/12
K= -41/12
K= -3 5/12
If there is a fraction with more then one of the same number repeated behind the decimal, it is a repeating decimal
