Answer:
The percent error is 40%
Step-by-step explanation:
To calculate the error percentage we have to divide the final amount over the initial amount
350 / 250 = 1.4
then we subtract 1 since this represents the estimated value
1.4 - 1 = 0.4
this is the error factor we have, to express it as a percentage we simply multiply by 100
0.4 * 100 = 40%
The percent error is 40%

The least number 12500 need to be multiplied by to make it a perfect square is 5.
Corrected question;
By which least number should 12500 be multiplied to make them perfect squares
Step-by-step explanation:
Perfect squares are squares of whole numbers.
Like 4,9,16 etc.
For 12500, we need to first of all reduce it to its Lowest factors.
12500 = 2×2×5×5×5×5×5
Grouping the factors into pairs of thesame factors.
12500 = (2×2) × (5×5) × (5×5) × 5
Looking at the pairs of factors, we can observe that the last factor 5 need to be paired to make the number a perfect square.
So, when the number is multiplied by 5;
12500 × 5 = (2×2) × (5×5) × (5×5) × (5×5)
62500 = (2×2) × (5×5) × (5×5) × (5×5)
62500 = (2×5×5×5)^2 = 250^2
Hence, 62500 is a perfect square.
The least number 12500 need to be multiplied by to make it a perfect square is 5.
