Find each product. Express your answer as both a fraction and a decimal.  

1. $1.25\cdot\left(-\frac{3}{5}\right)$ 

   Step 1 (a):

   Change both numbers to fractions or decimals.

   Here, $1.25=\frac{5}{4}$.

   $\frac{5}{4}\cdot\left(-\frac{3}{5}\right)$

   Step 2 (a):

   Multiply.

   $-\frac{15}{20}$

   Is this in simplest form?

   Answer (a):

   $-\frac{3}{4}$ or $-0.75$

2. $\left(-3\frac{2}{7}\right)\cdot0.14$ 

   Hint (b):

   See part (a).

3. $-4.37\cdot(-5.2)$ 

   Answer (c):

   $22.724=\frac{5681}{250}$
