Question

1. Find six rational numbers between

Answer 1

Answer:

Step-by-step explanation:

1) a) 3.1,  3.2,   3.3,  3.4, 3.5,  3.6

b)

$\frac{3}{5}=\frac{3*2}{5*2}=\frac{6}{10}\\\\\frac{8}{5}=\frac{8*2}{5*2}=\frac{16}{10}$

Six rational numbers are:

$\frac{7}{10};\frac{8}{10} ;\frac{9}{10} ;\frac{10}{10} ;\frac{11}{10} ;\frac{12}{10}$

2) a )

$\frac{641}{2}=320\frac{1}{2}\\\\ b)\frac{1251}{3}=417$

4)Simplify

$a)\frac{22}{3} *\frac{21}{5}=\frac{22*21}{3*5}\\\\=\frac{22*7}{5}\\\\ =\frac{154}{5}=30\frac{4}{5}$

5)

a) coeeficient of x² =  1

b) coeeficient of x² = 0

c) coeeficient of x² =  (-1)
