3. The equivalent ratio of 90:30 is
a) 36:12 b)12:36 c) 40:160 d)160:40​

Answer 1

HI MATE!!

Answer:

answer will be (a)36:12

Step-by-step explanation:

here we have 90:30

if we simplify it we will get,

=90/30

=9/3

=3/1

so the ratio 90:30 can also be written as 3:1

so now we just have to see the options and find the option whose value is equivalent to 3:1

let's see 1st option that is :- (a)36:12

if we simplify it then we will get,

=36/12

=18/6

=9/3

=3/1

so we find that option (a)36:12 is equivalent to 3:1 then it will also be equivalent to 90:30 as 90:30 is equivalent to 3:1

hence (a) is the correct answer and we don't need to see other options as the 1st option is correct!!!
