Question

can I get solution for these questions
plz​

Answer 1

1) I am sorry, I can't see the full question

2) 3.2 + 5.4 = 8.6

3)2/3 + 5/4 = 5/4 + 2/3

6) 0.351 = 351/1000

7) 0.3 + 0.4 + 0.5 = 1.2

8) Additive Identity = 0

9) solution:-

LCM of 5, 15 & 45 = 45

$\frac{4}{5} \times \frac{9}{9} = \frac{36}{45} \:$

$\frac{25}{15} \times \frac{3}{3} = \frac{75}{45}$

10 = 10

$\frac{21}{45} = \frac{21}{45}$

now,

$\frac{36 \: + \: 75 \: }{45} = \frac{111}{45} = \frac{111 \: - \: 10}{45} = \frac{101 \: + \: 21}{45} = \frac{122}{45}$
