How would your answer change if the pictures were 10 inches wide? Explain. Write your answer in the space below.

Answer 1

the wall -- 9.75 ft

the window ---- 5.75 ft

each picture----- 6 in ft

the space available to place the pictures is

9.75-5.75=4ft

1.

the space available to place the pictures is

9.75-5.75=4ft

we do this operation because we can't place the pictures in the window so we need to subtract the length of the window

2. 1 ft ---- 12 in

4ft --- 48 in

3. we can know if we divide 48 in between 6 the length of each picture

48/6=8

we can place 8 pictures

4. if we change the length of the pictures we can put only four pictures because they are bigger

48/10 = 4.8

but as we can't put an incomplete picture the result reduces to 4
