1:-

0.25

it should be in p/q form

$\\ \rm{:}\twoheadrightarrow 0.25$

$\\ \rm{:}\twoheadrightarrow \dfrac{25}{100}$

$\\ \rm{:}\twoheadrightarrow \dfrac{1}{4}$

q not equal to zero hence proved

2:-

Its Slightly false.

Counter example :-

The sum of two rational numbers is may be rational. The sum of two irrational numbers is always irrational.”

ex:-

$\\ \rm{:}\twoheadrightarrow \dfrac{1}{2}+\dfrac{1}{2}$

$\\ \rm{:}\twoheadrightarrow 1$

3:-

NOTA

$\\ \rm{:}\twoheadrightarrow 6(94)+7+(3+2)$

$\\ \rm{:}\twoheadrightarrow 564+7+5$

$\\ \rm{:}\twoheadrightarrow 576$

Jinny is selling bracelets for $4.00. So far, she has earned $296.00. She needs to earn more than $472.00 in order to meet her g

Darya [45]

She needs more then 472 and has 296 so she still needs 176 because 472-296=176
Each bracelets is 4 so then 176/4 is 44
1. She needs to sell 44 more bracelets,45 if she needs more than 472
2 the inequality would be x>=44 bracelets
