Marcos reads 3, books in 1 3/4 weeks.

Fofino [41]

Answer:

$x = \frac{12}{7}\ books$

Step-by-step explanation:

Given

$3\ books = 1\frac{3}{4}\ weeks$

Required

Number of books in 1 week

Represent the number of books in 1 week with x.

So, we have:

$3\ books = 1\frac{3}{4}\ weeks$

$x = 1\ week$

Cross Multiply

$x * 1\frac{3}{4} = 3 * 1$

$x * 1\frac{3}{4} = 3$

Convert fraction to improper fraction

$x * \frac{7}{4} = 3$

Multiply through by $\frac{4}{7}$

$x * \frac{7}{4}*\frac{4}{7} = 3 * \frac{4}{7}$

$x = 3 * \frac{4}{7}$

$x = \frac{12}{7}\ books$

<em>Hence: 12/7 books were read in a week</em>
