Question

what must be added to 5 whole 1/2 to get 11 whole 1/2​

Answer 1

Answer:

6 should be added to 5½ to get 11½.

Step-by-step explanation:

Here, in this question first we will assume that x should be added to 5½ to get 11½, which means sum of x and 5½ is equal to 11½. Thus, forming an adequate equation and doing the required calculations, we can easily find out the value of x, which is equal to the required number.

Let the required number be x.

According to the problem,

• 5½ + x = 11½

Solving the mixed fraction,

• 11/2 + x = 23/2
• (11 + 2x)/2 = 23/2
• 11 + 2x = 23/2 × 2
• 11 + 2x = 23
• 2x = 23 - 11
• 2x = 12
• x = 12/2
• x = 6
