You estimate that a baby pig weighs 21 lbs but it weighs 28 lbs what is the percent of error
lbvjy [14]
Your estimate of the baby pig's weight is 2 pounds. However the actual weight of it is only 16 pounds.
Let's solve for the percentage error of this.
=> 20 - 16 = 4 pounds
=> 4 / 16 = 0.25
=> 0.25 * 100% = 25%
Thus, you added 25% of the baby pig's weight

63% of what number is 252
storchak [24]

Answer:

We have, 63% × x = 252

or,

63/100 × x = 252

Multiplying both sides by 100 and dividing both sides by 63,

we have

x = 252 \times  \frac{100}{63 }

x = 400
