Question

At a pie eating contest sam ate 12 1/2 pies in 3 3/4 minutes. How many pies did he eat in a minute?

Answer 1

Answer: 3 1/3

Step-by-step explanation:

12 1/2 : 3 3/4=25/2 : 15/4=$\frac{25}{2}$:$\frac{15}{4}$=$\frac{25}{2}$*$\frac{4}{15}$=$\frac{10}{3}$=3 1/3

Answer 2

Answer:

$\text { Sam ate } 3 \frac{1}{3} \text { pies in one minute. }$

Step-by-step explanation:

$\text { At a pie eating contest sam ate }=12 \frac{1}{2} \text { pies in } 3 \frac{3}{4} \text { minutes }$

$12 \frac{1}{2} \text { it means } \frac{25}{2}$

$3 \frac{3}{4} \text { it means } \frac{15}{4}$

Let x be the number of pies ate in one minute.

$\text { He ate } \frac{25}{2} \text { pies in } \frac{15}{4} \text { minutes. }$

We need to find x pies in 1 minute.

Now we can find number pies x  

$\frac{25}{2} \text { pies }=\frac{15}{4} \text { minutes }$

x pies = 1 minute

By cross multiplying we get,

$\frac{25}{2} \times 1=\frac{15}{4} \times x$

$x=\frac{25 \times 4}{2 \times 15}$

$\text { The number pies ate in one minute }=\frac{100}{30}$

$\text { The number pies ate in one minute }=\frac{10}{3}$

$\text { He spend time on eating each pie }=3 \frac{1}{3} \text { pies }$

$\text { Therefore, sam ate } 3 \frac{1}{3} \text { pies in one minute. }$
