Lesson 16

Find the quotients:

1. $24 \div \text-6$
2. $\text-15 \div 0.3$
3. $\text-4 \div \text-20$

Find the quotients.

1. $\frac25 \div \frac34$
2. $\frac94 \div \frac {\text{-}3}{4}$
3. $\frac {\text{-}5}{7} \div \frac {\text{-}1}{3}$
4. $\frac {\text{-}5}{3} \div \frac16$

Is the solution positive or negative?

1. $2\boldcdot x=6$
2. $\text-2\boldcdot x=6.1$
3. $2.9 \boldcdot x = \text-6.04$
4. $\text-2.473\boldcdot x = \text-6.859$

Find the solution mentally.

1. $3 \boldcdot \text-4 = a$
2. $b \boldcdot (\text-3) = \text-12$
3. $\text- 12 \boldcdot c = 12$
4. $d \boldcdot 24 = \text-12$

Find the products.

1. $(100) \boldcdot (\text-0.09)$
2. $(\text-7) \boldcdot (\text- 1.1)$
3. $(\text-7.3) \boldcdot (5)$
4. $(\text-0.2)  \boldcdot (\text-0.3)$
