Question

A piece of string is cut into two lengths in a
ratio of 3:4. If the smaller length is 90 cm, what
is the other length?

Answer 1

Answer:

Now since the string is the ratio

3:5

So the longer piece/shorter piece=5/3

Let the shorter piece be x cms

Then,

20/x=5/3

20*3/5=x

X=12 cm

Answer 2

Answer:

ratio 3:4=3/4

smaller length: other length                               (other length =x)

so, 3/4=90/x                                                       (let's compare both to find x)

x=90*4/3

x=30*3*4/3

x=120cm                                                           (3 has been canceled from )
