Follow these rules:
Multiply and divide before adding and subtracting.
(1/4)(1/4) = 1/16, so now we have 1/16 - 1/4 ÷ 1/4 ÷ 1/4 ÷ 1/4
1/4 ÷ 1/4 = 1, so now we have 1/16 - 1 ÷ 1/4 ÷ 1/4
1 ÷ 1/4 = 4, so now we have 1/16 - 4 ÷ 1/4
4 ÷ 1/4 = 16, so now we have 1/16 - 16
1 - 256
and this simplifies to -15 15/16, or ------------
16

Answer:
I. 1 cup is $4.50
2 cups is $9.00
3 cups is $13.50
ll. 6 cups is $27.00
Step-by-step explanation:
Now since the number of cups is proportional to the total cost of frozen yoghurt,and the cost of 4 yoghurts cups where given .ie. $18.00
then 1 cup is $18/4 which is $4.50 per one cup, thus the other cost of cups are given.
therefore 6 cups is 6•18/4 which is $27.00.
hence 5 cups is 5•18/4 which is $22.50.
Solution:
Number of times a die is rolled = 20
1 - 3=A
2 - 5=B
3 - 4=C
4 - 2=D
5 - 3=E
6 - 3=F
Total number of arrangements of outcomes , when a dice is rolled 20 times given that 1 appear 3 times, 2 appears 5 times, 3 appear 4 times, 4 appear 2 times , 5 appear three times, and 6 appear 3 times
= Arrangement of 6 numbers (A,B,C,D,E,F) in 6! ways and then arranging outcomes
= 6! × [ 3! × 5! × 4!×2!×3!×3!]
= 720 × 6×120×24×72→→[Keep in Mind →n!= n (n-1)(n-2)(n-3)........1]
= 895795200 Ways
I can answer 18 for you, but I don't understand 16
18. Since when we lose 3 girls the ratio for the girls side drops by 1, that tells us that 1 digit equals 3 people.
a) 5*3=15 so our answer is 15 girls.
b) 4*3=12 and 5*3=15 so 15+12, our answer would be 27
