Answer: 8 3/6= 17/2
4 3/8=35/8
2 2/4=5/2

Step-by-step explanation:
To convert a mixed number to a improper fraction you multiply the whole number part by the fractions denominator then you add that number to the numerator then you write the number on top of the denominator
Answer:
B
Step-by-step explanation:
4, 12, 36, 108, 324
What is clearly shown is that the pattern is
4 · 3 = 12
12 · 3 = 36
36 · 3 = 108
108 · 3 = 324
The answer is 4 · 3∧n, [B]
For example:
4 · 3∧0 = 4 · 1 = 4
4 · 3^1 = 4 · 3 = 12
4 · 3² = 4 · 9 = 36
4 · 3³ = 4 · 9 = 108
Answer:
200
Step-by-step explanation:
Jack share = 2/5 x 1/5 = 2/25
amount left over = 1 - (2/25 + 2/5) = 13/25
13/25 x t = 260
t = total amount of chocolate
t = (260 x 25) / 13 = 500
Davids share = 2/5 x 500 = 200
Answer:
Step-by-step explanation:
If two variables, x and y have a direct variation, it means that an increase in x would lead to a corresponding increase in y. A decrease on x would lead to a corresponding decrease in y.
Therefore, we would compare the scenarios to determine which is not a direct variation. The correct option is
d) Time taken will be less if number of workers are increased to complete the same work.
The rest are direct variation scenarios
