20g : 100g = 1metre : 500cm

Answer:

True

Consider the given ratio, 20g : 100g = 1metre : 500cm

20/100 = 1/500

We know that, 1 meter = 100 cm

So, 20g: 100g = 100cm : 500 cm

20/100 = 100/500

20/100 is further simplified by dividing both numerator and denominator by 20 we get,

= 1/5

100/500 is further simplified by dividing both numerator and denominator by 100 we

get,

= 1/5

Hence, 1/5 = 1/5

Therefore, 20g : 100g = 1metre : 500cm

"hello students welcome to little q a
video session
i am sev your maths tutor and question
for today
is simplify each of the following
expressions
first 3 plus root 3 into 2 plus root 2
second 3 plus root 3 into 3 plus root 3
third root 5 plus root 2 whole square
fourth root 5 minus root 2 root 5 plus
root 2
so we'll solve each one of them one by
one
let us take first one in the first one
your question is
3 plus root 3
and 2 plus root 2
these are the two brackets in the
multiplication let us open the bracket
so 3 first and then you have 2
plus root 2 then there is a plus
root 3 and again
2 plus root 2 this is how we open this
bracket
so 6 plus 3 root 2
plus 2 root
3 plus
root 2 into root 3
and this will give you 6
plus 3 root 2 plus
2 root 3 plus
root 6.
hence this is our answer for this
question
in the second question it has been asked
3 plus root 3
into 3 plus root 3
so these are those two similar brackets
let us take 3 plus root 3 as 3 plus root
3 whole square
these are the two multiplications 3 plus
root 3 plus root 3 which is 3 plus root
3 whole square
so now we can apply the formula of a
plus b whole square
that is 3 square plus
2 into 3 into root 3
plus root 3 whole square
p square is 9 6
root 3 plus 3
so 12 plus 6 root 3
is the answer for this third one
root 5 plus root 2 whole square
so a plus b whole square which is root 5
square
plus 2 root 5 into root 2
plus root 2 whole square
so 5 plus 2 root of 10
plus 2 so 7 plus 2 root 10
is the answer for this this is how we
simplify
fourth one root 5 minus root 2
root 5 plus root 2
which is a minus b a plus b which is a
square minus b
square hence root 5 whole square minus
root 2
whole square this will give you
5 minus 2 and that is 3
so this is our final simplification for
all four
