Answer:
16
Step-by-step explanation:
So if 4 numbers have an average of 14, that means to find the sum of all 4 numbers, you work backwards & multiply 4x14 to get 56.
Then 56-the sum of the 3 numbers you already have (11+12+17=40)
56-40=16
To double check, to find the average of 4 numbers that total 56, you divide 56 by 4 & get 14
Answer:
0.06euros (2dp)
Step-by-step explanation:
18 donuts = 0.50euros (50 cents)
1 donut = 0.03euros (2dp) (3 cents)
2 donuts = 0.06euros(2dp) (6cents)
To start you would turn 4 2/3 into a mixed number by multiplying 4 and 3 and adding 2. Your mixed number would be 14/3. Then, you want to find how many 2/3 yard long pieces of string will fit into 14/3 so you devid 14/3 by 2/3 and you get 7. So 7 2/3 yard pieces of string will fit into 4 2/3.
To check your work you can multiply 2/3 by 7 and you will get 4 2/3.
5×3=15 (total circles)
15÷6 = 2.5 ( circles each students get )
