THANK YOU!
What are your answers?
We'll be glad to check your answers and help you understand these problems and their solutions.
1. 10
2. 10
3. 2/5 of 10= 4
4. 2/7 of 28= 8
All are correct! :-)
Excellent, thank you!
To find the product of a whole number and a fraction, you multiply the whole number by the numerator of the fraction and then divide the result by the denominator. Here's how to solve each of the problems:
1. 1/2 of 20 is:
Multiply the whole number (20) by the numerator (1):
20 * 1 = 20
Now divide the result by the denominator (2):
20 / 2 = 10
Therefore, 1/2 of 20 is 10.
2. 2/3 of 15 is:
Multiply the whole number (15) by the numerator (2):
15 * 2 = 30
Now divide the result by the denominator (3):
30 / 3 = 10
Therefore, 2/3 of 15 is 10.
3. Two-fifths of ten:
Multiply the whole number (10) by the numerator (2):
10 * 2 = 20
Now divide the result by the denominator (5):
20 / 5 = 4
Therefore, two-fifths of ten is 4.
4. Two-sevenths of 28:
Multiply the whole number (28) by the numerator (2):
28 * 2 = 56
Now divide the result by the denominator (7):
56 / 7 = 8
Therefore, two-sevenths of 28 is 8.
I hope this helps! Let me know if you have any other questions.
