Answer:
5.6 x 10 2
Step-by-step explanation:
Answer: 2 1/2 miles
Step-by-step explanation:
To subtract fractions with different denominators (in this problem they are 10 and 5), you have to find the least common denominator or LCD (10). Then you have to multiply the numerator and the denominator of 4/5 by 2 to turn the denominator into the LCD (10).
1. So 2 4/5 turns into 2 8/10
2. Then subtract 2 8/10 from 5 3/10 to get the answer 2 1/2
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.
