First no. = x
Second no. = y

Equation Formation
x + y = 55..........equation (i)
x - y = 1..............equation (i)

x = 1+y

1 + y + y = 55
1 + 2 y = 55
2 y = 55-1
2 y = 54
y = 27

x=27 + 1
x =28

Answer = 28 , 27

40 is 1/10 of 400 yes of no

kumpel [21]

YES!

You know it like this:

if something (x)is 1/10 of a whole(y), then you need 10 of this for the whole (y).

So the whole is then:

y=x*10

if x=40:

y=40*10=400,,

so yes, 40 is 1/10 of 400.
