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.

81. Each apple cost $0.50
82. One pound of chocolate = $3
Step-by-step explanation:

Let sold of 1 senior citizen ticket be "s", and
cost of 1 child ticket be "c"
First Day, 4 senior citizen ticket and 5 child tickets sold, equaled $46, so the equation we can write is:
Second Day, 3 senior citizen ticket and 1 child ticket sold, equaled $22, so the equation we can write is:
So, the system of equation (2 equations) written above can be solved simultaneously to find our answer.
81.
Let price of 1 apple be "a" and price of 1 banana be "b"
Since 3 apples and 2 banana cost $2, so we can write:
3a + 2b = 2
Then,
4 apples and 4 bananas cost $3, so we can write:
4a + 4b = 3
We can solve for the variable b in equation 1. Shown below:
Now we put this value of b into equation 2 and solve for cost of 1 apple, a. Shown below:
So each apples cost $0.5
82.
Let 1 pound of chocolate be cost "c"
Let 1 pound of peanut be cost "p"
4 lb of chocolate and 2 lb of peanut = $16, thus we can write:
4c + 2p = 16
Next,
2 lb of chocolate and 3 lb of peanut costed $12, so we can write:
2c + 3p = 12
We solve first equation for p:
Now, we put this expression for p into equation 2 and solve for c:
So, 1 pound of chocolates cost $3
