Step 1) Set up a proportion
Proportion: percent / 100 = x / number
In context of the problem, the proportion is: 40 / 100 = 10 / number
Step 2) Cross-multiply and solve
100 x 10 = 40 x N
1000 = 40N
N = 25
Answer: The number is 25
Answer:
Yasmine estimated the difference to be 82. The actual difference is 81.91.
Step-by-step explanation:
The rounded whole number of 87.71 is 88 and the rounded whole number of 5.8 is 6.
So, the difference between the numbers 87.71 and 5.8 by rounding each number to the nearest whole numbers will be
(88 - 6) = 82.
The actual difference between the numbers 87.71 and 5.8 is (87.71 - 5.8) = 81.91.
Therefore, Yasmine estimated the difference to be 82. The actual difference is 81.91. (Answer)
