Question

show that 30,40,45,60are in proportion
​

Answer 1

Answer:

1800=1800

Step-by-step explanation:

1)First we will write these numbers in two sides as rational number,such that 30/40=45/60

2) Now we will do cross multiply as 30×60=40×45

3)So after multiplying we have got 1800=1800.

therefore if RHS=LHS then it is in proportion and so it is also in proportion!!

I hope this will helpful to u!!
