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>
