Answer:

How much did they eat all together? 5/6

How much was left over? 1/6

\\

Step-by-step explanation:

How much did they eat all together?

\frac{2}{4}  +  \frac{1}{3}  \\  =  \frac{6}{12}  +  \frac{4}{12}  \\  =  \frac{10}{12}  \\  =  \frac{5}{6}

\\

How much was left over?

1 - \frac{5}{6}  \\  =  \frac{6}{6}  -  \frac{5}{6}  \\  =  \frac{1}{6}

Answer:

<em>Pizza eaten together: 5/6,</em>

<em>Pizza left over: 1/6</em>

Step-by-step explanation:

~ If Ellen ate 2/4th of the pizza and John ate 1/3 of the pizza, provided that the pizza counts as a whole ( 1 )... ~

1. Let us simplify 2/4th to be ⇒ 1/2, through simple algebra

2. To see how much they ate together we would neglect that the pizza counts as a whole but simply add 1/2 by 1/3rd.

3. Through simple algebra: 1/2 + 1/3 = 3/6 + 2/6 = <em>Pizza eaten together: 5/6</em>

4. Now to find out how much pizza was left over, we would need the fact that a pizza ⇒ 1 whole. It would be that 1 - 1/2 - 1/3 ⇒ Pizza left over, through the <em>Partition Postulate. </em>In fact, the pizza left over would simply be 1 whole - the pizza eaten together ( 5/6 ).

5. Through algebra: 1 - 1/2 - 1/3 = 1 - 5/6 = <em>Pizza left over: 1/6</em>

Estimate 58% of 112 using benchmark percents. Explain your answer.
vitfil [10]

Answer:

64.96

Step-by-step explanation:

The most common benchmark percents are 0\% , 10\% , 25\% , 50\% , 75\% and 100\%

We are given 58\% which is closest to 50\%.

Now we calculate 50\% \ of \ 112 which is equal to 56.

We are left with 8\% more to add.

We can say 1\% \ of \ 112 \ is\ 1.12

Therefore 8\% \ of \ 112 \ would \ be \ 1.12\times8=8.96

Now add the two.

56+8.96= 64.96

Thus 64.96 is the answer.

No is divisible by 7 if n is divided by 2 3 4 5 the remainder is 1 what is the smallest value that n could b
kvv77 [185]

Answer: 301

Step-by-step explanation:

Since, The LCM of numbers given numbers 2 ,3,  4 and 5 is 60.

Thus, the number that gives 1 as reminder and is the multiple of 7 is  60 n + 1

Where n is any positive integer,

Since, For n = 5,

The number is, 60\times 5 + 1 = 300 + 1 = 301

Which is divisible by 7.

Thus, the required number is 301.

Note : For n = 1, 2 3 and 4, numbers are 61, 121, 181 and 241

But they are not the multiple of 7.

Alja [10]

The first sequence, it is increase +1 for every number, because 2-3 is 1, 3 - 5 is 2, and 5 - 8 is 3. So, lets add 4 to 8, and we will know the next number of the sequence.

4 + 8 = 12

So, the next number in the first sequence is:

1, 1, 2, 3, 5, 8, 12

Second Sequence:

The second equation is doing exactly the same thing (it increases by 1 every number it goes) just this one is decreasing.

Proof: 26 - 24 is 2, 24 - 21 is 3, and 21 - 17 is 4.

Lets subtract 5 to 17 to know the next number.

17 - 5 = 12

So our next number is:

26, 24, 21, 17, 12
