UNIDAD DIDÁCTICA 4: FRACCIONES. FRACTIONS.

FRACCIÓN – FRACTION

FRACCIONES EQUIVALENTES – EQUIVALENT FRACTIONSIf the cross-products are the same, then the fractions are equivalent.

the first cross-product is 2 · 15 = 30 . The second cross-product is 5 · 6 = 30. So,these fractions are equivalent. 

½ is the simplest fraction SIMPLIFICANDO FRACCIONES  – SIMPLIFYING FRACTIONS 

If we keep dividing until we can't go any further, then we

have simplified the fraction (made it as simple as possible).

MULTIPLICANDO FRACIONES  - MULTIPLYING FRACTIONSMultiply the top numbers (the numerators).

Multiply the bottom numbers (the denominators).

DIVIDIENDO FRACCIONES - DIVIDING FRACTIONSMultiply the first fraction by the reciprocal of the second fraction.

Multiply the cross-product.

COMPARANDO Y ORDENANDO  – COMPARING AND ORDERINGTHE SAME DENOMINATORS.

The largest fraction is the one with largest denominator.

DIFERENT DENOMINATORS.If the cross-products are equal, then the fractions are equivalent.

If the first cross-product is the largest, then the first fraction is the largest.

If the second cross-product is the largest, then the second fraction is thelargest

SUMANDO FRACCIONES – ADDING FRACTIONSTHE SAME DENOMINATORS.

Add only the top numbers (numerators)DIFERENT DENOMINATORS. 

Find the LCM of the denominators. It’s the new denominator of both

fractions.

We divide every new denominator by the previous one, and we multiplythe result by each numerator.
