Answer 1

Answer:

Step-by-step explanation

4. Let the numbers be 7x and 9x

Sum 9x +7x = 112

16x= 112

x=7 so the numbers are 7*7=49

And 9*7 =63 so the larger number is 63

5. Ratio 384:480 in simplest form will be 1st divide both by 96 u will get simplest form as 4:5

6. Let the shares of A,B,C be 2x, 3x and 5x

Total amount =1200

So, 2x+3x+5x= 1200

10x= 1200

x=120

Now, as b's share is 3x then his share amount will be 360

7. As we know speed=distance/time

So speed of bus = 126/3 = 42km/hr

And speed of train = 315/5 =63 km/hr

Then the ratio of their speeds will be

42:63 when we divide both of them by 21 then we will get this ratio in simplest form which is 2:3
