56\div 8=7

Step-by-step explanation:

The relationship of division and subtraction:

If a\div b=c then a-bc=0            (Definition 1)

The given equation is

56\div 8=7

We need to prove this by subtraction.

Let 56\div 8=x

Here, a= 56 is dividend, b=8 is divisor and c=7 is quotient.

56-8=48    (1st time)

48-8=40    (2nd time)

40-8=32    (3rd time)

32-8=24    (4th time)

24-8=16    (5th time)

16-8=8    (6th time)

8-8=0    (7th time)

It means we need to subtract 8 (total 7 times) from 56 to get 0.

56-8\times 7=0

Using definition (1) , we get

56\div 8=7

Hence proved.

To check whether Camden's answer is correct, we need to find the subtraction equation that would represent dividing 56 flowers equally into 8 bouquets, where each bouquet contains 7 flowers. Let's go through each option:

Option 1: 56 - 7 - 7 - 7 - 7 - 7 - 7 - 7 - 7 = 0
Here, Camden subtracted 7 from 56 for each of the 8 bouquets. If this equation is true, it means that he distributed all 56 flowers into 8 bouquets, leaving none behind. However, calculating this equation gives us 56 - 49 = 7, not 0. So this equation is not correct.

Option 2: 56 - 8 = 48
This equation is incorrect because Camden divided the total number of flowers by the number of bouquets, which is not what he did. He distributed 7 flowers into each of the 8 bouquets, not 8 flowers.

Option 3: 56 - 7 - 7 - 7 - 7 - 7 - 7 - 7 = 0
This option correctly represents Camden's division of 56 flowers into 8 bouquets, where each bouquet contains 7 flowers. Subtracting 7 from 56 for each bouquet, 8 times, gives us 56 - 56 = 0. Therefore, this equation is correct.

Option 4: 56 - 7 = 49
This equation represents subtracting 7 flowers once from the total number of flowers, but it doesn't properly represent dividing the flowers into bouquets. This equation is not correct for Camden's situation.

So, the subtraction equation that Camden could use to check his answer is:
56 - 7 - 7 - 7 - 7 - 7 - 7 - 7 = 0

By subtracting 7 flowers from the total of 56, eight times, he ensures that all 56 flowers are distributed equally into 8 bouquets, each containing 7 flowers.

So first he has to divide both sides by 8
wat
he multiplied the right side by 8 but divided left by 8
that is wrong

answer is 4th option
divid not divide 56 by 8
