I need help with this problem.
Estimate 16 20/21 times 28 3/7
minus 4 13/25 plus 8 2/47 as a whole
number or as a mixed number where the
fractional part is 1/2
(Possible answers) One is the correct
answer.
A. 452
B. 480
C. 488
D. 492 1/2
I have tried to work this and keep
coming up with 476. Which I know is
wrong. Because the correct answer is
A,B,C, or D.
Will you please try to help!!!
Thank you so very much!!
Will someone please help?
I would say C 488.
You are meant to estimate to wholes or halves so round the numbers...
17*28.5-4.5+8=488
Not exactly what I would call "estimation" but that is the best result I can see given your choices...
What is one-eighth times 17?
To calculate one-eighth times 17, you simply multiply the fraction and the whole number.
One-eighth times 17 can be calculated as:
(1/8) * 17 = (1 * 17) / 8 = 17 / 8
So, one-eighth times 17 is equal to 17/8, which is a mixed number.
