To work out the expression -22 2/5 - 1 1/4 x (-2 1/2), you'll need to follow the order of operations (also known as PEMDAS/BODMAS).
Step 1: Multiply
Start by multiplying -1 1/4 and -2 1/2. This can be done by converting the mixed numbers into improper fractions and then performing the multiplication. Here's how you do it:
-1 1/4 can be written as -5/4
-2 1/2 can be written as -5/2
Now multiply the numerators and denominators:
(-5/4) x (-5/2) = 25/8
Step 2: Subtract
Now, you need to subtract 25/8 from -22 2/5. Again, convert the mixed number into an improper fraction and then subtract. Follow these steps:
-22 2/5 can be written as -112/5
Now subtract 25/8 from -112/5:
(-112/5) - (25/8) = -896/40 - 125/40 = -1021/40
Therefore, the answer to the expression -22 2/5 - 1 1/4 x (-2 1/2) is -1021/40.
