Answer these questions if you know, if you dunno then don't answer!!!!! Answers should be with statements

Answer:
1. first take LCM of all denominators
i.e. LCM of 5 and 6= 30 and 6 ,15=30
= 30÷5×1 – 30÷6×1 ÷ 30÷6×1 – 30÷15×1
30 30 30 30
= 6 –5 ÷ 5–2
30 30
= 1 ÷ 3
30 30
= 1 × 30
30 3
= 1
3
2. = 3×7+3 ÷ 5×7+1 + 2×4+1
7 7 4
= 24 ÷ 36. + 9
7 7 4
= 24 × 7 + 9
7 36 4
= 2 + 9
3 4
LCM of 3 and 4= 12
= 8 + 27
12 12
= 35 = 2 whole 11/12
12
3. first, do cross multiply then,
6(2x-3)=4(x+5)
12x-18 =4x+20
12x-4x=20+18
8x =38
x=38÷8
x=19/4
4. x:12::48:x
product of extremes = product of means
x × x =12×48
x^2 =576
x=√576
x=24
5. Area of rectangle = L×B
80.75 = 9.5×B
80.75÷9.5= B
8.5=B
6. 5x+4x+3x=180
12x =180
x=180÷12
x=15
7. = [(2)^2×3 × 3^6]×(6)^6
= [2^6×3^6]×6^6
= 6^6 × 6^6
= 36^6
10. 2x-11=13
2x=13+11
2x=24
x=24÷2
x=12
sorry, I can't answer 8th and 9th question.
I HOPE IT HELPS YOU ..
