# Math homework 7th grade easy ?

40/50=_\100

Relevance
• Look at the 100. What would you need to do to the 50 to make it into 100?

So you have this

40

-----

50

=

X

---

100

in order to turn the 50 into 100 you would need to multiply the 50 x 2 . Whatever you do to the denominator you must also do to the numerator. so you would multiply the 40 x 2 as well so you have this

40 x 2 = X

-------------- -----

50 x 2 = 100

and x = 80

You multiply the fraction by 2/2, which is really just 1, in order to get the fraction out of 100.

take a 0 off each one so it becomes 4/5=_/10 so then you can see that 5 goes into 10 twice so you times the 4 by two so its eight then add the zeros back in, simple answer is 80 :)
