Question

please tell the answer of three of them with explanation

Answer 1

2/3+1/3=3/3 = 1
7-1/4 - 1/4= 7×4/1×4 - 1/4 =28/4 -1/4 =27/4
16/5+29/6 =96/30+145/30=241/30
hope it helps

Answer 2

1) (1+2)/3= 3/3=1 {the denominators are same}
2) {(4*7)-1}/4
=(28-1)/4
=27/4
=6.75. {first multiple 7 with 4 as to get 4 as lcm}
3) 16/5 + 29/6
now do lcm
.: lcm = 30
={(16*6) +(29*5)}/30
={96+145}/30
=241/30
=8.0333333~
=8.03
