Question

for every 9 customers, a chef prepares 2 loaves of bread. here is your double number line and table from the previous screen. how many loaves are needed for 63 customers? if the chef prepares 20 loaves, how many customers can they serve?

Explanation:

First Sub - Question: How many loaves are needed for 63 customers?

Step1: Find the ratio multiplier

We know that for 9 customers, 2 loaves are prepared. To find out how many groups of 9 customers are in 63 customers, we calculate $63\div9 = 7$.

Step2: Calculate the number of loaves

Since each group of 9 customers requires 2 loaves, for 7 groups, the number of loaves is $2\times7=14$.

Second Sub - Question: If the chef prepares 20 loaves, how many customers can they serve?

Step1: Find the ratio multiplier

For 2 loaves, 9 customers are served. To find out how many groups of 2 loaves are in 20 loaves, we calculate $20\div2 = 10$.

Step2: Calculate the number of customers

Since each group of 2 loaves serves 9 customers, for 10 groups, the number of customers is $9\times10 = 90$.

Answer:

For 63 customers, 14 loaves are needed.
For 20 loaves, 90 customers can be served.
