What is 75% of 44 cookies
Alecsey [184]

Answer: 33 cookies.

Step-by-step explanation: To find the 75% of 44 cookies, use these steps:

Step 1: Our output value is 44.

Step 2: We represent the unknown value with x.  

Step 3: From step 1 above, 44 = 100%.

Step 4: Similarly, x = 75%.

Step 5: This results in a pair of simple equations:

  • 44 = 100%(1)
  • x = 75%(2)

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right-hand side) of both equations have the same unit (%); we have:

  • \frac{44}{x} \\ = \frac{100 percent}{75 percent}

Step 7: Again, the reciprocal of both sides gives:

  • \frac{x}{44} = \frac{75}{100}
  • x = 33

Therefore, 75% of 44 is 33. Thus, it is 33 cookies.
