Question

Answer the questions. Be prepared toa. How many people will 10 cupsof rice serve?

Answer 1

EXPLANATION

Given that 2 cups of dry rice serves to 6 people we can compute the rate in order to get the people for 10 cups:

`rate=\frac{6\text{ people}}{2\text{ cups}}\cdot10\text{cups}=30\text{ people}`

a) We can say that 30 people will serve from 10 cups.

b) In order to get the number of cups that are needed to serve 45 people, we can also apply the unitary method as shown as follows:

`\text{rate}=\frac{10\text{ cups}}{30\text{ people}}\cdot45\text{ people=15 cups}`

In conclusion, we can say that 45 people will serve from 15 cups.
