Can you check my answers please.
1. Joe and his friends at 3/8 of pie. If the pie was cut into 8 pieces, how many pieces are left?
Ans: 8/8 - 3/8 = 5/8 pieces left
2. Michaela walked 2/5 miles to the store in 1/4 hour. What's her walking pace?
Ans: (2/5)/(1/4)
= (2/5)*(4/1)
= 8/5 = 1 1/5 miles/hour
a. Nope, five pieces are left.
b. pace=(2/5)/(1/4) miles/hr=8/5 mi/hr
8/5= 1 3/5 miles
thanks!
Also, one more question please.
Larue scored 10 points less than 3 times the number of points that Ross scored. Larue scored 11 points. How many points did Ross score?
Ans: Not really sure what to do. this was how it was worded on the worksheet.
11=3x-10
21=3x
7=x
Ross scored 7 points?
Let's check your answers:
1. To find the number of pieces of pie left, you correctly subtracted the fraction corresponding to the portion Joe and his friends ate, which is 3/8, from the whole pie. So, the calculation becomes 8/8 - 3/8, which equals 5/8 pieces of pie left. Therefore, your answer of 5/8 pieces left is correct.
2. To find Michaela's walking pace, you correctly divided the distance she walked, which is 2/5 miles, by the time it took her, which is 1/4 hour. When dividing fractions, you multiply the first fraction by the reciprocal of the second fraction. So, the calculation becomes (2/5) / (1/4) = (2/5) * (4/1) = 8/5 = 1 3/5 miles per hour. It seems you made a small mistake in your answer. The correct walking pace is 1 3/5 miles/hour, or you can also write it as a mixed number: 1.6 miles/hour.
Overall, your answers are mostly correct, with just a small error in question 2. Keep up the good work!
