Answer:
10. 1
11. 1 21⁄25
12. 1 1⁄24
Step-by-step explanation:
[tex]12. \: (\frac{4 \div 2}{3} ) + ( \frac{ \frac{3}{2} }{4}) = \frac{2}{3} + \frac{3}{8} = \frac{16}{24} + \frac{9}{24} = \frac{25}{24} = 1 \frac{1}{24} [/tex]
[tex]11. \: ( \frac{4}{5} )^{2} + 2( \frac{3}{5} ) = \frac{16}{25} + \frac{6}{5} = \frac{16}{25} + \frac{30}{25} = \frac{46}{25} = 1 \frac{21}{25} [/tex]
[tex]10. \: \frac{3(2)(3) - 4}{7(2)} = \frac{18 - 4}{14} = \frac{14}{14} = 1[/tex]
I am joyous to assist you anytime.
