please give my answer as much fast as you can!!!​

Answer 1

• No they are not equal.

$\frac{13}{39} \: it \: is \: a \: prime \: number \: ratio \: and \: \frac{7}{21} \: is \: simlpy \: \frac{1}{3} .$

• Length = 200m, Breadth = 175m, Height = 150m

Length : Breadth = 200 m : 175 m = 8 : 7

Length : Height = 200 m : 150m = 4 : 3

• 20 mins to 3 hours.

3 hours = 3 x 60 mins = 180 mins

20 mins : 180 mins = 1 : 9

• 1m = 100 x 10 mm

1000 mm = 1m, 2mm : 1000mm = 1 : 500

• 12 : 24 = 1 : 2

32 : 64 = 1 : 2

As we can see clearly that they both are equal.

• 1 : 2 = x +2x = 3x

3x = 60 pens

x = 60/3 = 20 pens

x pens for Shikha = 20 pens for shikha

2x pens for Sheena = 20 x 2 pens = 40 pens to Sheena.

• 52.7 : 30 :: a : 150

Let it be like this

$\frac{52.7}{30} = \frac{a}{150} \\ a = 52.7 \times \frac{150}{30} \\ a = 263.5$

• 55 people in HR department.

Total = 150 people

Let the number of working maintenance people be x

150 = x + 25 + 55

x = 70 people of working maintenance

55 : 70 = 11 : 14 (option (d) none of the above).

HAVE A NICE DAY!!!
