Answer:
2 1/4
Step-by-step explanation:
In an equilateral triangle, all 3 sides are the same length. If one side length is x, the perimeter is x+x+x or 3x which is equal to 6 3/4 as said in the problem. You get the equation 3x=6 3/4. Dividing both sides by 3, you get x=2 1/4.
Answer:
C. 3 5/18
Step-by-step explanation:
What we know:
Joel purchased 5 7/9 lb of grapes, while Jim purchased 2 1/2 lb.
What we need to find out:
How many more pounds of grapes does Joel have than Jim.
What we need to do:
Subtract 2 1/2 from 5 7/9.
But first, we need a common denominator.
2 and 9 don't have any common factors so multiply normally.
2 * 9 = 18
5 7/9 becomes 5 14/18, and 2 1/2 becomes 2 9/18.
Now to subtract.
(5 - 2) + ((14-9)/18)
3 + ((14-9)/18
3 + 5/18
Joel has 3 5/18 more pounds of grapes than Jim, so the answer is C.
Two numbers are relatively prime if they have no common divisors other than 1. This is the case only for a) , the common divisor in other cases is:
b: 3
c: c
d: 18
