Question

Totsakan enlarged the size of a photo to a height of 18 inches. what is the new width if it was originally 2 inches tall and 1 inch wide

Answer 1

I would set up a proportion and then solve for the width, which is x. Know how to set one up?

Answer 2

no can you help me?

Answer 5

So a porportion looks like this

(Number) x
------- = ------
(Number) (Number)

The first fraction will consist of the 2 numbers of the original photo

The second fraction will consist of x (What you're looking for), and the given number that goes along with it. Try setting that up and ill check it.

Answer 6

2
---- =x
1 ---
18?

Answer 9

Almost, you just had the 1 and 2 flipped

1 x
- = --
2 18

Now, to solve this.. you can do numerous things. For this specific problem: You see the first number is a half and the equal sign, which means the number on the right also has to be a half. So what number would x have to be so it is half of 18?

You could also cross multiply and divide, which is diagonally multiplying (hint, you need both numbers and not one can be an x) and then divide by the number you didnt use

Answer 10

x has to be nine right

Answer 11

can you help with one more?

Answer 12

Yes, it's 9. And sure!

Answer 13

ok a frame is 9in, wide and 6in, tall if it is reduced to a width of 3in, then how tall will it be?

Answer 14

i dont get it

Answer 15

So this one is like the last question, but alittle backwards. You would also set up the proportion though

You would make a fraction with the original numbers of the frame, put an equal sign, and then put x

Answer 16

x
--
(new width)

Answer 17

So the original dimensions are 9 and 6 right? Put that into a fraction

Answer 18

3 x
-- = --
9
6

Answer 19

Not exactly, for the 3/6 fraction, the 3 was not the original width of the frame, so the 3 shouldn't be in the first fraction

Answer 20

And also you wanna match heights and widths when you scan across

width new width
----- = --------
height new height

for example

Answer 21

oh so like 9=3
----
3=x

Answer 22

The top is right, but for the bottom, I think you put the wrong number. Check the original dimensions again, and you should be good

Answer 23

opps i meant 6

Answer 24

Yep, so you get:

x 6
- = -
3 9

Think you can solve this one? It's like the first one, the steps that is

Answer 25

ok is i one or two?

Answer 26

So for the bottom one, what number multiplied by 3 will give you 9?

Answer 27

3

Answer 28

Right, so you do the same for the top. What number multiplied by 3 will give you 6?
