Question

A grocery store sells steaks for $6.10 a pound what would the cost of 2 3/5 pound of steak beat

Answer 1

$15.86

1) Considering that a grocery store sells steaks at this price, we can write out the following ratios:

$\begin{gathered} lb------\ \\ 1------6.10 \\ 2\frac{3}{5}-----x \end{gathered}$

Notice that for our convenience, we can convert that Mixed Number into an Improper Fraction following this procedure:

$2\frac{3}{5}=\frac{5\times2+3}{5}=\frac{13}{5}$

2) Now we can write out the following ratios, and then cross multiply them:

$\begin{gathered} \frac{1}{\frac{13}{5}}=\frac{6.1}{x} \\ x=6.1\times\frac{13}{5} \\ x=15.86 \end{gathered}$

Note that we dealt with decimal numbers and fractions.

3) Hence, the price of 2 3/5 lbs of steak is $15.86
