Answer 2

same as the other question! cross multiply

Answer 3

alternatively you can simplify both fractions first so when you cross multiply you don't get such a big number

Answer 4

ok

Answer 5

Same steps! Different numbers!

Answer 6

Cross multiply:
s * 26 = 39 * 18

Answer 7

though people use "cross multiply" it's not very efficient
the easiest way is to multiply both sides by the 39, like this
\[ \frac{39}{39} s = \frac{18\cdot 39}{26} \]
on the left side 39/39 is 1 so you get
\[ s = \frac{18\cdot 39}{26} \]

Answer 8

ok thank you @phi

Answer 9

Simplifying
s * 26 = 39 * 18

Answer 10

ok

Answer 11

the other "trick" is to try to divide the top and bottom by the same number *before* multiplying out the top.
to use this trick, you should learn a few of the rules for what numbers divide into another
for example: if a number is even, then 2 divides into it
if the sum of the digits is divisible by 3 , then the number is divisible by 3
for example, for 18, 1+8=9 and 9 is divisible by 3 so you know 18 is also

Answer 12

Looks like you don't need my help.

Answer 13

ya i do @Qwertty123 even if i don't your still my freind

Answer 14

oh okay! :)

Answer 15

Reorder the terms for easier multiplication:
26s = 39 * 18

Answer 16

Then you:
Multiply 39 * 18
26s = 702

Answer 17

I would start by dividing the top 18 by 2 and the bottom number 26 by 2
you get
\[ s= \frac{9\cdot 39}{13} \]
if you write 39 as 3*13
you have
\[ s= \frac{9\cdot 3\cdot 13}{13} \]
it should be clear what to divide top and bottom by to simplify more

Answer 18

Then you do these steps!
Solving
26s = 702

Solving for variable 's'.

Move all terms containing s to the left, all other terms to the right.

Divide each side by '26'! :D What do you get when Dividing each side by 26?

Answer 19

26/26=1

Answer 20

@Qwertty123

Answer 21

from 26s=702
divide both sides by 26. So you're right on one side coz you'll get
1s=702/26 which is?
