D— put 7 over 1 and then change division sign to multiplication & then flip 9/5 to 5/9
1111.111 in expanded form is 1000 + 100 + 10 + 1 + 0.1 + 0.01 + 0.001
<span>q=1/2p+15
1/2p = q - 15
p = 2q - 30

3/6+1/6+1 2/3
Make 1 2/3 into an improper fraction:
5/3
Give them all common denominators by multiplying both sides of 5/3 by 2:
10/6
Then the question becomes:
3/6+1/6+10/6
Now you add the numerators and the denominator stays the same:
14/6
Now you can simplify by dividing both sides by 2:
7/3
Now you can make it a mixed number:
2 1/3
Hope this helps :)
