3. a) 2/3 parts of the distance between two places is 30 km. (1) Find the distance between the places. (ii) Find 3/5 parts of the distance between the places .

i.45km and ii.

Step-by-step explanation:

i.if 2/3=30km then ,2/3=30/1 multiply (3)(30)/(2)(1)=90/2=45km

&

ii.3/3=45, so 3/5=? it is also equal to 3/3=3/5 this means 45/1=3/5

multiply (45)(5)/(3)(1)=225/3=75

Step-by-step explanation:

Solution

we know that

2/3=30km

Now

let X be the total distance

X=30÷2

or X=15

therefore X=15×3

=45km

answer: 2 and 1
