Adding and subtracting fractions 5th grade

Step-by-step explanation:

To add fractions there are Three Simple Steps:

Step 1: Make sure the bottom numbers (the denominators) are the same.

Step 2: Add the top numbers (the numerators), put that answer over the denominator.

Step 3: Simplify the fraction (if needed)

There are 3 simple steps to subtract fractions

1) Make sure the bottom numbers (the denominators) are the same.

2) Subtract the top numbers (the numerators). Put the answer over the same

denominator.

3) Simplify the fraction (if needed).

∠APD and ∠BPC are opposite angles, so ∠APD = ∠BPC

∠D = 180° - ∠APD - ∠1 = 180° - ∠BPC - ∠2 = ∠B

ΔAPD ≈ ΔBPC because they have the same angles.
