Write About the Math

Of the USED storage, approximately what percent are photos — and why does the whole change from 6 GB to 4 GB for this question?Del almacenamiento usado, ¿aproximadamente qué porcentaje son fotos — y por qué el entero cambia de 6 GB a 4 GB en esta pregunta?

Say your answer to a partner first. Then write it, using at least two of these words:

estimateestimación benchmark percentporcentaje de referencia compatible numbersnúmeros compatibles double number linerecta numérica doble the wholeel todo

Model: 4 GB sits between two benchmark landmarks on the number line, closer to the 75% mark, so a reasonable estimate lands near there without computing the exact fraction. — A strong answer names both landmark percents (50% and 75%) and explains why 4 GB sits closer to one than the other. A weak answer just says 'it's close to 70%' without placing it between benchmarks.
