5.    4

6.    2

7.     9

8.     2.04

9.     3/40

10.   10 raised to power - 5

11.     1

Step-by-step explanation:

4.  1/2+1/3

Lcm of 2 and 3 is 6 so let both denominators by 6

$\frac{1}{2} *\frac{3}{3} = \frac{3}{6} \\\\\\\frac{1}{3} *\frac{2}{2}=\frac{2}{6} \\\\\frac{3}{6} +\frac{2}{6} =\frac{5}{6}$

5. $2*\frac{1}{4} *8= \frac{2}{4} *8= 4$

6. 2

7.

$\frac{5}{x} =\frac{125}{225}\\ \frac{125}{225}= \frac{25}{45}= \frac{5}{9}\\\frac{5}{x} = \frac{5}{9\\} \\therefore x=9$

8. 2.04

9.  For,

expressing 0.075 as a fraction in lowest term  

=75/1000  

=3/40  

Therefore,0.075 expressed as a fraction in lowest terms will be 3/40

10. $a^{4}b * b$

11. $\frac{1}{10^{8-3} } = \frac{1}{10^{5} } = 10^{-5}$
