What must you do to the first inequality to get to the second inequality? A. N 4 <5;n<20 b. − n 4 <5;n>−20 A. A. Add

adell [148]

A. You have two inequalities:

$\dfrac{n}{4}$
$n$

If you multiply the first inequality by positive number 4 (multiplying inequality by positive number doesn't change the inequality sign), then you get the inequality

$4\cdot \dfrac{n}{4}$

B. You have two inequalities:

$-\dfrac{n}{4}$
$n>-20.$

If you multiply the first inequality by negative number -4 (multiplying inequality by negative number changes the inequality sign), then you get the inequality

$-4\cdot \left(-\dfrac{n}{4}\right)>-4\cdot 5,\\ \\n>-20.$

Answer: option D.

What is the quotient of 4 2/3 divided by 4 1/5 :fraction

Ostrovityanka [42]

Write the two fractions as improper fractions
4 2/3 is 14/3
4 1/5 is 21/5
rewrite
14/3 ÷ 21/5
since it is pretty complicated to divide two fractions,
you change it to multiplication
keep the first fraction, change the division sign to multiplication, then flip the second fraction
(you can remember KEEP, CHANGE, FLIP whenever dealing with division of fractions :) )
14/3 * 5/21
multiply across
(14 * 5) / ( 3 * 21)
70/ 63
simplify to 10/9
this can be written as 1 1/9

Hope this helps
