Tab 1: Visual Tape Diagrams & Double Number Lines

Partition a 100% tape into equal sections to find the exact value of each section and calculate the required percent.

Divide una barra del 100% en partes iguales para encontrar el valor de cada sección y calcular el porcentaje pedido.
📏 100% partitioned into 5 parts = 20% each
Model 1 of 8

Tab 2: The Percent Equation (Part = Percent × Whole)

Two-step algebraic method: convert the percent to a decimal (or fraction), then multiply by the whole base.

Convierte el porcentaje a decimal (o fracción) y luego multiplícalo por el total (base) para hallar la parte.
📝 Part = Decimal × Whole (e.g. 0.25 × 80 = 20)

Tab 3: Comparing Percentages with Different Wholes

A higher percentage does not always mean a higher quantity! Calculate the actual part for each group to compare.

¡Un porcentaje más alto no siempre significa una cantidad mayor! Calcula la cantidad real de cada grupo para comparar.
⚖ 70% of 40 (28) vs. 60% of 50 (30)
