Question

In a grapefruit eating contest, Sal ate 5 1/3 grapefruits in 2 minutes. If the world record is 7 1/6 grapefruits in 3 minutes, how many grapefruits would Sal have had to eat in the next minute to tie the record

Answer 1

Answer:

Sal would have to eat 1 5/6 grapefruits.

Step-by-step explanation:

We have been given that Sal ate 5 1/3 grapefruits in 2 minutes.

And the world rec-ord is 7 1/6 grapefruits in 3 minutes.

So in the 3rd minute Sal would have to eat x  grapefruits in order to tie the record.

It means we have the phrase

x plus 5 1/3 equal 7 1/6

Mathematically, we have

$x+5 1/3=7 1/6$

Subtract 5 1/3 to both sides of the equation

$x=7 1/6-5 1/3\\\x=\frac{43}{6}-{16}{3}\\\\x=\frac{43-32}{6}\\\\x=\frac{11}{6}\\\\x=1\frac{5}{6}$
