1. mutliply 3.and 3/5 enter your answer as an improper fraction in simplified form in the box.
natali 33 [55]

Answer:

1.\frac{9}{5}

2.-11\frac{1}{4}

3.10\frac{1}{8}

4.4\frac{17}{24}

5.-4\frac{7}{12}

Step-by-step explanation:

In order to solve them you just have to multiply them and add them:

3 (\frac{3}{5} )=\frac{15+3}{5}=\frac{18}{5}

-4\frac{1}{2}  (2\frac{1}{2} )=-(\frac{9}{2} )(\frac{5}{2}) =-(\frac{45}{4}) =-11\frac{1}{4}

(-2\frac{1}{4} )(-4\frac{1}{2}) =(-\frac{9}{4}) (-\frac{9}{2} )=-\frac{81}{8} =-10\frac{1}{8}

3\frac{3}{8}+ 4\frac{1}{3}=7\frac{8+9}{24} =7\frac{17}{24}

-2\frac{1}{4} +-2\frac{1}{3}=-4\frac{7}{12}
