Answer:

B) 6

Step-by-step explanation:

$7\frac{1}{2}(\frac{3}{5}) + 1\frac{1}{2}$

convert mixed fractions to improper

$= \frac{15}{2}(\frac{3}{5}) + \frac{3}{2}$

multiply numerators 15*3 and denominators 2*5 where you multiply fractions

$= \frac{45}{10} + \frac{3}{2}$

find a common denominator, 10. for 3/2, multiply top and bottom by 5.

$= \frac{45}{10} + \frac{15}{10} = \frac{45+15}{10}$

$= \frac{60}{10}$

$= 6$ <= reduced to lowest terms
