Momo's Fractional Feast: Fractions comic
Pizzafest Park. Momo's class is having a picnic.
Momo: Yay! Pizza day at Pizzafest!
The Sum Goblin: Ha! 1/2 + 1/3 = 2/5! Who cares about halves and thirds?
Momo: Wait, that can't be right! Pieces aren't the same size!
Matching pieces
When adding fractions, pieces match.
Can't add 1/2 and 1/3 directly.
Find common size first.
Momo: Oh! We need to make pieces the same size first.
The Sum Goblin: See? 1/2 + 1/3 = 2/5. Half and third don't add like that!
Momo: Half and third don’t match. Let’s make them match!
1/2 = 3/6
1/3 = 2/6
3/6 + 2/6 = 5/6
Add with common sizes
Find the common denominator first.
Change to same denominator.
Then add the numerator like normal.
Momo: Always find a common denominator first. Then it’s easy!
Your turn, hero!
The Sum Goblin♥♥♥
Momo had 1/4 of a pizza and then ate 1/6 more. How much pizza did he eat?
5/12. (1/4) + (1/6) = 3/12 + 2/12 = 5/12
The Sum Goblin: Silly kids. Just learn my trick. 2/5 is all you need!
To add 1/3 + 1/6, what is the common denominator?
6. 3 × 2 = 6, so 6 is the common denominator.
The final battle
The Sum Goblin♥♥♥
Momo eats 1/2 of a cake and his friend eats 1/4. How much cake is that?
3/4. 1/2 + 1/4 = 2/4 + 1/4 = 3/4.
The Sum Goblin: Wrong, wrong! How will you fix this?
Momo: Common denominator, get it? Find the right size first!
Everyone gets equal slices now. The Sum Goblin's trick fails!
The End?
Villain card won! Answer again in a few days and it turns gold.
