BGBGBGB

Now boys can be arranged among themselves in 4! ways, and girls among themselves in 3! ways,

So total no. of ways 

= 4 ! × 3 ! = 144

Explanation

Let's evaluate the equation:

(1/4 + 5/8) = 2/8 + 5/8 = 7/8

(1/2 + 3/4) = 4/8 + 6/8 = 10/8 = 5/4

Add the two expressions:

(7/8) + (5/4) = 7/8 + 10/8 = 17/8

So, the equation evaluates to 17/8.

Therefore, the correct answer is 17/8.

Explanation

Let the product of two real numbers = ab

One number =9

9a=72

A= 72/9

A=8

Explanation

To convert 0.50% to a fraction:

To simplify:

0.0050 = 5/1000

= 1/200

Explanation

120% of 40 = (120/100) * 40

= 1.2 * 40

= 48

Explanation
