Question

change mm and dm 100m​

Answer 1

Answer:

Step-by-step explanation:

1 m =10 dm

100m =100*10=1000 dm

1 m =10 dm

100m =100x10=1000 dm

1m =1000 mm

100 m=100x1000=1,00,000 mm

i) 8 : 5 :: 2 :x

multiplication of outer no = multiplication of inner two numbers

So 8x=5x2

x=5x2/8=10/8=5/4

ii) 3:x::2:4

2x=3x4

x=12/2=6

iii) 4:3 :: x:1

3x=4x1

x=4/3

i) 8 : 5 :: 2 :x

multiplication of outer no = multiplication of inner two numbers

So 8*x=5*2

x=5*2/8=10/8=5/4

ii) 3:x::2:4

2x=3*4

x=12/2=6

iii) 4:3 :: x:1

3x=4*1

x=4/3
