Question

1. a satellite makes 1\frac{4}{6} revolutions of the earth in three days. which of the following expressions shows how many revolutions the earth would make in 1 day?

a. 1\frac{4}{6}\div3
b. 3\div1\frac{4}{6}
c. 1\frac{4}{6}\div2
d. 1\frac{4}{6}\div\frac{1}{3}

Explanation:

Step1: Recall rate - calculation concept

To find the number of revolutions per day, we divide the total number of revolutions by the total number of days.

Step2: Identify given values

The satellite makes $1\frac{4}{6}$ revolutions in 3 days.

Step3: Write the expression

The expression to find the number of revolutions in 1 day is the total revolutions $1\frac{4}{6}$ divided by the number of days 3, i.e., $1\frac{4}{6}\div3$.

Answer:

A. $1\frac{4}{6}\div3$
