Answer:
A. n
Step-by-step explanation:
n/4 + n/4 + n/4 + n/4 = 4n/4 = n
To find the answer you need to write equivalent fractions with larger denominators. If you multiply each fraction by 3/3 then your equivalent fractions would be
3/5 × 3/3 = 9/15
4/5 × 3/3 = 12/15
Now we have two fractions that are equivalent to the original fractions and we can easily see that 2 fractions between 9/15 and 12/15 would be...
10/15 and 11/15
(10/15 can reduce to 2/3 so your answers could also be 2/3 and 11/15)
the answer is d to the question
Answer:
b=3
Step-by-step explanation:
If b is inversely proportional to c then
b is 5 when c is 12, means...
From where we obtain the value of k, the constant needed, which is equals to 5*12=60
Now... to find b when c=20, is just a matter of using our known variables.
