Question

in the united states in 2018, approximately 8,000,000,000 pennies were produced, and approximately 2,000,000,000 quarters were produced. how many times as many pennies were produced as quarters?
divide the leading factors, 8 ÷ 2.
\\(\frac{\text{number of pennies}}{\text{number of quarters}} = \frac{8,000,000,000}{2,000,000,000} = \frac{8 \cdot 10^9}{2 \cdot 10^9}\\)
\\(= \frac{8}{2} \cdot \frac{10^9}{10^9}\\)
\\(= \square \cdot ?\\)

Explanation:

Step1: Dividir el coeficiente

Divide \( \frac{8}{2} \), lo que da \( 4 \).

Step2: Dividir los exponentes de 10

Para \( \frac{10^9}{10^9} \), al dividir potencias con la misma base, restamos los exponentes: \( 10^{9 - 9} = 10^0 = 1 \).

Step3: Multiplicar los resultados

Multiplicamos el resultado del coeficiente y el resultado de los exponentes de 10: \( 4 \times 1 = 4 \).

Answer:

4
