3.2 0.57 of 425
3.3 0.25 of 100

Answer 1

To estimate percentages of numbers, divide or multiply by a close value and round to the nearest whole number.

Step-by-step explanation:

3.1 To estimate 25% of 786, we can divide 786 by 4 since 25% is equivalent to 1/4. 786 divided by 4 is 196. So, 25% of 786 is approximately 196.

3.2 To estimate 0.57 of 425, we can multiply 425 by 0.6 since 0.57 is close to 0.6. 425 multiplied by 0.6 is 255. So, 0.57 of 425 is approximately 255.

3.3 To estimate 0.25 of 100, we can multiply 100 by 0.3 since 0.25 is close to 0.3. 100 multiplied by 0.3 is 30. So, 0.25 of 100 is approximately 30.
