Buffyyour study buddyHi! Ask me about equivalent fractions, comparing, adding fractions, or "fraction of".

A fraction is just a part of a whole — and once you can see it on a bar, equivalent fractions, comparing, and adding all stop being scary. Drag the bar and watch.
Play with it
Set the denominator (how many equal parts) and the numerator (how many you take). Watch the bar fill — and see the same amount written as a decimal and in its simplest form.
3/4 = 0.75 — a proper fraction, already in simplest form.

A fraction names a part of a whole (or of a collection). In 3/4, the denominator (4) is how many equal parts the whole is cut into; the numerator (3) is how many of those parts you take.
Multiply or divide the top and bottom by the same number and the value doesn't change — these are equivalent fractions: 1/2 = 2/4 = 3/6. Divide by the HCF to reach the simplest form (6/8 → 3/4).
To compare two fractions, give them the same denominator (use the LCM), then just compare the numerators:
Worked example. Add 1/4 + 1/6.
LCM of 4 and 6 is 12. Rewrite: 1/4 = 3/12 and 1/6 = 2/12.
Now the denominators match: 3/12 + 2/12 = 5/12.
Where you'll meet it
Half the recipe? Every quantity halves: 3/4 cup becomes 3/8. Splitting 3 rotis among 4 people gives each 3/4 of a roti — a fraction is literally "share fairly".
"1/3 off" a ₹600 shirt saves ₹200. "Three-quarters of an hour" is 45 minutes. Knowing "fraction of" turns these into one quick multiplication.
