Question

2) 1 2/5*2 5/7-1 2/5*3/14 _______ 3) 1/9*1 5/6+1 1/6*1/9

Answer 1

2) = 1 2/5 * (2 5/7 - 3/14) = 1 2/5 * (2 10/14 - 3/14) = 1 2/5 * 2 7/14 = 1 2/5 * 2 1/2 = 7/5 * 5/2 = 7/2 = 3 1/2

3) = 1/9 * (1 5/6 + 1 1/6) = 1/9 * 2 6/6 = 1/9 * 3 = 3/9 = 1/3

Answer 2

To solve the expression, we need to follow the order of operations:

1. First, we need to perform the multiplication and division operations from left to right.
2. Then, we need to perform the addition and subtraction operations from left to right.

So, let's start:

1 2/5 * 2 5/7 = (7/5) * (19/7) = 133/35

1 2/5 * 3/14 = (7/5) * (3/14) = 3/10

Now we can substitute these values in the original expression:

133/35 - 3/10 = (1332)/(352) - (37)/(107) = 266/70 - 21/70 = 245/70 = 7/2

Therefore, the value of the expression is 7/2.

To solve the expression, we need to follow the order of operations:

1. First, we need to perform the multiplication and division operations from left to right.
2. Then, we need to perform the addition and subtraction operations from left to right.

So, let's start:

1/9 * 1 5/6 = (1/9) * (11/6) = 11/54

1 1/6 * 1/9 = (7/6) * (1/9) = 7/54

Now we can substitute these values in the original expression:

11/54 + 7/54 = 18/54 = 1/3

Therefore, the value of the expression is 1/3.
