Question

write the correct symbol $(-, div)$ or number in each box to complete the equations.

1. a restaurant cooks 60 cups of rice. each side order of rice is $\frac{3}{4}$ cup of rice. how many side orders of rice can they serve?

$60\square \frac{3}{4} = 60 \times \frac{\square}{\square} = \square$ orders

Explanation:

Step1: Determine the operation

To find the number of side orders, we divide the total cups of rice (60) by the cups per order ($\frac{3}{4}$). Dividing by a fraction is equivalent to multiplying by its reciprocal. So the operation in the first box is $\div$.

Step2: Find the reciprocal

The reciprocal of $\frac{3}{4}$ is $\frac{4}{3}$, so the second box (numerator) is 4 and the third box (denominator) is 3.

Step3: Calculate the result

Now we calculate $60\times\frac{4}{3}$. $60\div3 = 20$, and $20\times4 = 80$. So the last box is 80.

Answer:

The first box: $\div$, the second box: $4$, the third box: $3$, the last box: $80$. So the completed equation is $60\div\frac{3}{4}=60\times\frac{4}{3}=80$ orders.
