Part A
The number of members in the equal-size groups will be the Greatest Common Divisor of the numbers 20 and 25. That number is 5. There are several ways to find this number. One way is to look at the prime factors of 20 and 25:
20 = 2*2*5
25 = 5*5
The largest factor common to both is 5.
There will be 5 students in each group.
Part B
The number of groups is the number of students divided by the size of the group.
There will be 20/5 = 4 groups of sixth graders.
There will be 25/5 = 5 groups of seventh graders.
Answer:
1.2 units
Step-by-step explanation:
2.6(d + 1.4) - 2.3d = 4
2.6d + 3.64 - 2.3d = 4
0.3d + 3.64 = 4
0.3d = 0.36
d = 1.2
250:100
To solve this ratio, we should simplify it:
25:10
5:2
The ratio is 5:2
The unit price for best cookies is $0.5
The unit price for Okay cookies is $0.4
Step-by-step explanation:
The unit cost is obtained by dividing the total cost by the quantity
Given
<u>Best Cookies:</u>
Cost = $6.00
Quantity = 12
So the unit price will be:
<u>Okay Cookies:</u>
Cost = $8.00
Quantity = 20
The unit price is:
The unit price for best cookies is $0.5
The unit price for Okay cookies is $0.4
