Question

If a 12 ounce box of cereal costs $3.84, how many ounces should be in a box marked $2.49?

Answer 1

Answer:

• 7.78 ounces

Step-by-step explanation:

We know that:

• 12 ounce box of cereal = $3.84

Work:

• 12/3.84 ounce box of cereal = $1
• => 12/3.84 x 2.49 box of cereal = $2.49
• => 7.78 ounces (Rounded to nearest hundredth) = $2.49

Hence, 7.78 ounces cost $2.49.

Answer 2

7.8125 ounces

Step-by-step explanation:

Based on given conditions,

$\frac{2.49 \times 12}{3.84} \\ = > \frac{ \frac{249}{100} \times 12 }{ \frac{384}{100} }$

$= > \frac{ \frac{249}{25} \times 3 }{ \frac{96}{25} }$

$= > \frac{249}{25} \times 3 \times \frac{25}{96}$

$= > 83 \times 3 \times \frac{1}{32}$

$= > \frac{83 \times 3}{32}$

$= > \frac{249}{32}$

$= > 7.78125ounces$

By rounding off,

$= > 7.9ounces$
