Question

convert. round to the nearest hundredth if necessary. find the width in inches of 35-mm film. in

Answer 1

we are converting in to mm so we need to know the conversion factor. How many in in 1 mm. We will have to look that up.  It turns out there are .03937in in every mm.

So we need to get rid of mm so we want that on the top left and bottom right

35mm      .03937in

---------- x --------------

      1              1mm

 

the mm units cancel and we can multiply to get 1.37795in

we need to round that to the nearest hundredth. Since the thousandths place is greater than 5 we round up to

1.38in

Answer 2

The perimeter of a rectangle is 206 inches. The length exceeds the width by 27 inches. Find the length and the width.
