Question

I need help, I'll fan and medal

Answer 1

what is it on?

Answer 2

How do you get 1 7/8

Answer 3

Do you mean how did 1 7/8 come out of no where?

Answer 4

yes

Answer 5

So you can add, multiply, divide, subtract any number on an equation as long as it is is on both sides.

Answer 6

So technically you could just multiply both sides by 5 if you wanted.

Answer 7

so that's how they got 1 7/8???

Answer 8

never mind I think we are thinking about different parts

Answer 9

so they just combined the positive 4 and the negative 5 7/8

Answer 10

to get -1 7/8

Answer 11

it's not negative sign tho

Answer 12

the 5 7/8 was negative

Answer 13

isn't it just subtraction?

Answer 14

yeah, pretty much, but since the negative is bigger the answer is negative

Answer 15

So, you have 8 = d - 1 7/8

You want to get d by itself, right? So how would you get the 1 7/8 to the other side of the equal sign?

Answer 16

um inverse property of multiplication??

Answer 17

idk

Answer 18

Basically you do opposites

You see it's - 1 7/8

The opposite of multiplication is division, for example

So what's the opposite of subtraction (Since you're subtracting in the problem d - 1 7/8)

Answer 19

addition

Answer 20

Right, so you would add 1 7/8 to both sides

Answer 21

wait how did you get 1 7/8?

Answer 22

Because the original was 8 = d - 1 7/8

When you try to get the d by itself, you add 1 7/8, because that's the number on the same side of the variable d

Answer 23

If that made any sense

Answer 24

But isn't the original equation: 8= 4 + d - 5 7/8?

Answer 25

Omg, I didn't see that part!

Yes it is. What the author did was a conversion. Would you know how to convert 4 into a fraction over 8?

Answer 26

Basically 4 = ?
---
8

Answer 27

ok

Answer 28

Hint: Cross multiply those two numbers to get the answer

Answer 29

ok I got 47/2 that's probably way off...

Answer 30

Remember 4 also equals 4/1, so basically its 4/1 = ?/8. So lets figure out the denominator. 1 times what number equals 8?
