Question

PLS HELP WILL MARK YOU BRAINLIEST!! No fake answers pls

Answer 1

#1

$\boxed{\dfrac{a}{b}=\dfrac{b}{a},a=b}$

Here 5$\neq 3$

Hence inequality holds

#2

$\\ \sf\longmapsto 7-(4+3)=(4+3)-7$

$\\ \sf\longmapsto 7-7=7-7$

$\\ \sf\longmapsto 0=0$

Equality holds

#3

$\\ \sf\longmapsto (x+y)+1=x+(y+1)$

Equality holds

Done

Answer 2

Answer:

1. 5/3 is not equal to 3/5.

2. 7-(4+3) is equal to (4+3)-7

3. (x + y) + 1 is equal to x + (y + 1)

Step-by-step explanation:

1. 5/3 and 3/5 are completely different fractions and when you switch the denominator and the numerator you get a different fraction: 5/3 = 1 2/3, 3/5

2. If you solve both of them, they are equal because 7-7 = 7-7

3. This is equal due to the associative addition property, which means that when the addition of three or more numbers, the total/sum will be the same, even when the grouping of addends are changed.
