Answer 1

Answer:

a) 43:9 (I don't know if this is right but the question is not understandable so I wrote it in improper fraction. So please forgive me if it's a mistake. But I didn't understand the question well.)

b) 63:45:35

c) 1:3

d) 378:675:980

Step-by-step explanation:

a) 43:9

9*4+7/9

= 43/9

b) 63:45:35

1/5*315:1/7*315:1/9*315 (Because 315 is the LCM of 5,7,9)

63:45:35

c) 1:3

0.25*4:0.75*4

= 1:3

d) 378:675:980

1 whole 1/5: 2 whole 1/7: 3 whole 1/9

= 6/5:15/7:28/9

= 6/5*315:15/7*315:28/9*315

= 378:675:980

Answer 2

So ,LCM of 5,7,and9 is the product of 5×7×9

(1/5) 7×9:1/7 5×9: 1/9 5×7

7×9: 5×9 : 7:5

63: 45: 35

the answer is 63: 45: 35
