Answer: same numbers
Step-by-step explanation:
You should write a ( real world situation ) question that can only have whole numbers as a solution because you would divide and then you can not have a fraction left over so instead you add one. For instance there are 132 students going on a field trip. 20 students can fit on each bus. how many buses are needed? 7 because when you divide 132 by 20 you get 6 remainder 12. You can not just make 12 students walk to the location so you would add an extra bus.
Answer:
10 years old
Step-by-step explanation:
Let's say the age of the younger sister is x. Then the age of the older sister must be x + 2 because the ages are consecutive <em>even</em> numbers.
"Twice the age of the youngest exceeds the oldest by 8" means that we multiply x by 2 and set that equal to (x + 2) + 8:
2x = (x + 2) + 8
2x = x + 10
x = 10
So, the youngest sister is 10 years old.
Answer:
$30
Step-by-step explanation:
3/3 - 1/3 = 2/3
The fraction shows how much she has left.
2/3 = $20
1/3 = $20 ÷ 2 = $10
3/3 = $10 x 3 = $30
Each bag costs $8.30 each since 138/16.50 is around $8.30
