First you convert the whole number into a fraction. Since you already have a fraction of 5/16, convert 2 into 16th's, which would be 32/16. Add 5/16 to 32/16 and you have 37/16. Divide 16 into 37, and your result will be a decimal. Your final answer will be 2.3125. I hope this helps!
What is the question? i could help you if i knew the question
The constant of proportionality is 3
Answer:
The identity element of Q is 0, and 0 ∈ Z. Finally, if n ∈ Z, its additive inverse in Q is −n. But −n is also an integer, so Z is closed under taking inverses. Therefore,Z is a subgroup of Q.
