Answer 1

Answer:

• 4/3 bag of coffee can be used for 8 hours.

Step-by-step explanation:

• Paul needs 2 bags of coffee every day for his cafe.
• He has only 4/3 bag of coffee.
• Paul's cafe is open for 12 hours a day.

To Find:

• How long 4/3 bag of coffee can be used?

Solution:

1. 2 bags of coffee is used in 1 day at the cafe.
2. The cafe is opened for only 12 hours a day.

From 1 and 2, we get,

2 bags of coffee can be used for 12 hours.

Now,

$\sf{\longmapsto2\; bags=12 \;hours}$

$\sf{\longmapsto1\; bag=\dfrac{12 \;hours}{2}}$

$\sf{\longmapsto1\; bag=6\;hours}$

Hence,

• 1 bag of coffee can be used for 6 hours.

Now,

$\sf{\longmapsto1\; bag=6\;hours}$

$\sf{\longmapsto\dfrac{4}{3}\; bag=\left(6\times\dfrac{4}{3}\right)\;hours}$

$\sf{\longmapsto\dfrac{4}{3}\; bag=\left(2\times4\right)\;hours}$

$\sf{\longmapsto\dfrac{4}{3}\; bag=}\;\bf{8\;hours}$

Hence,

• 4/3 bag of coffee can be used for 8 hours.
