Answer 3

To solve this expression, let's break it down step by step:

-7/8 * 4/7 - (-3/20)

First, simplify the fractions:

-7/8 * 4/7 = -28/56 * 4/7 = -1/2 * 4/7

Next, multiply the fractions:

-1/2 * 4/7 = -2/7

Now, we have:

-2/7 - (-3/20)

To subtract a negative number, we can rewrite it as addition:

-2/7 + 3/20

Next, find a common denominator, which in this case is 140:

-2/7 * 20/20 = -40/140 3/20 * 7/7 = 21/140

Now we have:

-40/140 + 21/140

Combine the fractions:

-40/140 + 21/140 = -19/140

So, the result is -19/140.
