6:7
start by setting up the ratios as fractions and using <em>x</em> as the variable.

next cross multiply.

x=10 i believe
To solve these types of questions, all what you need to do is simply solve for any one of the variables provided above and substitute the solved variable for the other equation. For instance in the first example:
X/2 - 2y = 5
12y + X - 2 = 0
X = 2 - 12y
(2 - 12y)/2 - 2y = 5
(2 - 12y)/2 = 2y + 5
2 - 12y = 2(2y + 5)
2 - 12y = 4y + 10
16 y + 8 = 0
16y = -8
Y =-8/16 = -1/2.
X = 2 - 12(-1/2)
X = 2 + 6
X = 8.
P(X, y) = P(8, -1/2).
Do the same method, for the other questions, except simplify them before doing so.
Answer:

What is 2/5 * 7/10
7/10 x 2/5 = 7/25
Step-by-step explanation:
As you Can See Here I have Explained how to Multiply Fraction.
we multiply two fractions, such as 7/10 x 2/5, we simply multiply the numerators by each other and the denominators by each other.
To multiply the two fractions, first multiply the top numbers by each other, then multiply the bottom numbers by each other,
___________________________________________________________
7/10 and 2/5 = ?
1. Multiply both numerators
7 x 2 = 14
2. Multiply both denominators
10 x 5 = 50
Which Equals 14/50
14/50 is an equivalent fraction for 7/10 times of 2/5, and its simplified term is 7/25.
Therefore Making the Answer 7/25.
