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

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

Change both numbers to fractions or decimals.

Here, $1.25=\frac{5}{4}$.

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

Multiply.

$-\frac{15}{20}$

Is this in simplest form?

$-\frac{3}{4}$ or $-0.75$

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

See part (a).

3. $-4.37\cdot(-5.2)$

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