Question

Complete each statement.

If 4a=45, then a/5= ____ and a/9= ____ .

if 10k=25, then 2k=___ and k/5=___.

if m+p/p = 12/5, m/p=___, and p/m___.

Answer 1

4a = 45
a =45/4
then a/5 =... ?

Answer 2

where did 5 came from?

Answer 3

it was in the question!

Answer 4

If 4a=45, then a/5= ____

Answer 5

oh sorryy.. yes, that's the question. but I could not figure it out.

Answer 6

a =45/4
did u get this ?

Answer 7

9 x 5 = 45
so.. a/5= a/9 ?

Answer 8

or maybe 9/4 ?

Answer 9

\(\huge \color{blue}{4a=45 \\a=\frac{45}{4}\\ \frac{a}{5}=\frac{45}{4*5}=\frac{9}{4}}\)
yes, 9/4 is correct.

Answer 10

what about a/9 =.. ?

Answer 11

and a/9 would be 5/4

Answer 12

\(\huge \color{blue}{4a=45 \\a=\frac{45}{4}\\ \frac{a}{9}=\frac{45}{4*9}=\frac{5}{4}}\)
good!

Answer 13

solve the 2nd one in same way.....10k =25
k=... ?

Answer 14

how is it like? its 2k= __ ?
k=25/10.
=5*5/10
I am confused.

Answer 15

you are going good.
\(\huge \color{blue}{10k=25 \\k=\frac{25}{10}\\2k=\frac{2*5*5}{2*5}=...? }\)

Answer 16

2k = 5 ?
divide both sides by 5

Answer 17

yes, u can do that also, and u get k = 5/2

Answer 18

and 2k what was asked for =5
what about k/5=... ?

Answer 19

k/5 = k/2

Answer 20

how you getting k on right side also ??

Answer 21

k/5 is just 1/2

Answer 22

Wait.. if
k= 25/10
2k = 50 / 10
2k = 5

so.. k/5 = 1/2
because you multiply 2 and 5 in both sides.
Thanks!

Answer 23

yes! good :)

Answer 24

because you 'divide' 2 and 5 in both sides.

Answer 25

why is 10 not multiplied twice? but 25 is multiplied.

Answer 26

because '2' was multiplied to the 'numerator' of left side.
so 2 will be multiplied only to numerator of right side, that is to 25 only.

Answer 27

Ohh. Thankyou!

Answer 28

:)
tried 3rd ?

Answer 29

yes. m/p would be 7/5 ? and p/m = 5/7
did I get it correctly??

Answer 30

Answer 31
