Practice adding and subtracting fractions.
1/ Jill's friends met at her house to go on a hike to the lake.they walked 1/4 of the way and then rested. How much further do they have to go to reach the lake?
I don't know
2/ When they reached the lake , they took a swim.Jill swam 2/3 across the lake and then swam back to shore. If she had continued, how much further would she have had to swim to reach the other side?
3/ the hike back to Jill's house took an hour. They walked for 1/2 hour and stopped for a water break. How much longer did they have to hike to get back to Jill's house ? Write the answer in a fraction and in minutes.
4/ When they arrived at Jill's , her mother served them a deli sandwich. She cut the sandwich into 12 sections . Jill and her 8 friends each ate 1 section. How much of the sandwich was left over ? Answer with 2 equal fraction.
5/ for dessert, Jill sevred her friends a chocolate cake. It was cut into 14 slices . Tow of her friends don't eat chocolate. If everyone els had on slice , how much of the cake remained uneaten?
6/ Peter's mother picked him up at Jill's house after they ate . Then she drove to the market to buy food. The market is 1/3 of the way to Peter's house from Jill's . How far is Peter's house from the market?
Please,,
Help me, I tried but don't know solve each problem..
#1
1/4 + 3/4 = 1
They have gone 1/4, so they still have 3/4 of the way to go.
#2
2/3 + 1/3 = 1
so, she still had 1/3 of the way to go
#3
1/2 + 1/2 = 1
They had gone 1/2, so they still had 1/2 hr or 30 min to go
#4
1/12 + 8/12 + 3/12 = 1
They ate 9/12, leaving 3/12 = 1/4 left over
#5
of 9 people, 2 did not eat.
9/14 + 5/14 = 1
There were 5/14 uneaten
#6
No idea how far it was.
But, having gone 1/3 of the way, they still had 2/3 to go, or twice as far as they had already gone.
Sure! I'd be happy to help you solve each problem. Let's break down each question and work through them step by step.
1/ Jill's friends met at her house to go on a hike to the lake. They walked 1/4 of the way and then rested. How much further do they have to go to reach the lake?
To find out how much further they have to go, we need to subtract the distance they already walked (1/4) from the total distance to the lake. If we assume the total distance to the lake is 1, then the remaining distance would be 1 - 1/4.
So, the answer is 3/4.
2/ When they reached the lake, they took a swim. Jill swam 2/3 across the lake and then swam back to shore. If she had continued, how much further would she have had to swim to reach the other side?
Jill swam 2/3 across the lake, which means she has 1/3 left to swim to reach the other side.
So, the answer is 1/3.
3/ The hike back to Jill's house took an hour. They walked for 1/2 hour and stopped for a water break. How much longer did they have to hike to get back to Jill's house? Write the answer in a fraction and in minutes.
They walked for 1/2 hour, which means they have another 1/2 hour left to hike back to Jill's house.
So, the answer is 1/2 hour or 30 minutes.
4/ When they arrived at Jill's, her mother served them a deli sandwich. She cut the sandwich into 12 sections. Jill and her 8 friends each ate 1 section. How much of the sandwich was left over? Answer with 2 equal fractions.
Jill and her 8 friends ate a total of 9 sections from the sandwich (1 section each). To find out how much was left over, we need to subtract 9 from the total number of sections, which is 12.
So, the answer is 3/12 or 1/4.
5/ For dessert, Jill served her friends a chocolate cake. It was cut into 14 slices. Two of her friends don't eat chocolate. If everyone else had one slice, how much of the cake remained uneaten?
If two friends don't eat chocolate and everyone else had one slice, we need to subtract 2 from the total number of slices (14).
So, the answer is 12/14 or 6/7.
6/ Peter's mother picked him up at Jill's house after they ate. Then she drove to the market to buy food. The market is 1/3 of the way to Peter's house from Jill's. How far is Peter's house from the market?
To find the distance between Peter's house and the market, we need to multiply the total distance from Jill's house to Peter's house by 1/3.
Let's assume the total distance is 1. So, the distance from Jill's house to the market would be 1 * 1/3.
So, the answer is 1/3.
I hope this helps! Let me know if you have any more questions.
