Answer:
-135/14
Step-by-step explanation:
There are an infinite number of rational numbers between any pair of numbers you name. These two number have the decimal values ...
-67/7 = -9 4/7 = -9.571428... (repeating)
-78/8 = -9 3/4 = -9.75
So, numbers like -9.6 = -48/5, or -9.7 = -97/10 are rational numbers that lie in the range you specified.
If you like, you can convert these numbers to ones with a common denominator (56).
-67/7 = -536/56
-78/8 = -546/56
These limits suggest several possible rational numbers with 56 as a denominator: -540/56 = -135/14, for example.
[-½, ¾]; use either "Substitution" or "Elimination" to do this, and you'll see that this answer is correct.
Ratio:
Red : Total
2 : 5
(x2) (x2)
4 : 10
Green : Total
3 : 10
Total of red and green marbles = 4 + 3 = 7
Blue marbles = 10 - 7 = 3
10 parts = 40 marbles
1 part = 40 ÷ 10 = 4
3 parts = 4 x 3 = 12
Answer: There are 12 blue marbles.
