On a number line, between which two consecutive whole numbers would 78 be located? Choose the correct answer below.

OA. 8 and 9

OB. 10 and 11

C. 7 and 8

OD. 9 and 10

C ; 7 and 8

Step-by-step explanation:

The correct question is as follows;

On a number line, between which two consecutive whole numbers would 7.8 be located?

Solution

Here, we want to know between which consecutive whole numbers will 7.8 be located .

As we know, 7.8 is a decimal, it is same as 7 + 0.8

It is greater than 7 but less than 8;

Thus it is between 7 and 8

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
