To solve these multiplication problems, you need to multiply the numerators (top numbers) together and multiply the denominators (bottom numbers) together.
Let's go through each problem step by step:
1. -2/5 multiplied by -1 1/4:
First, we need to convert the mixed number -1 1/4 to an improper fraction.
-1 1/4 can be rewritten as -(4/4 + 1/4) = -(5/4).
Now, we can multiply -2/5 by -5/4:
(-2/5) x (-5/4) = (2/5) x (5/4) = 10/20 = 1/2
2. 1 2/5 multiplied by -3/4:
Again, we need to convert the mixed number 1 2/5 to an improper fraction.
1 2/5 can be rewritten as (5 x 1 + 2) / 5 = 7/5.
Now, we can multiply 7/5 by -3/4:
(7/5) x (-3/4) = (-21/20) = -1 1/20
3. -7/8 multiplied by -1 3/7:
Convert the mixed number -1 3/7 to an improper fraction.
-1 3/7 can be rewritten as -(7/7 + 3/7) = -(10/7).
Now, we can multiply -7/8 by -10/7:
(-7/8) x (-10/7) = (70/56) = 5/4
The answers are:
1. -2/5 x -1 1/4 = 1/2
2. 1 2/5 x -3/4 = -1 1/20
3. -7/8 x -1 3/7 = 5/4
