Is this proportion true or false

2/3
_____
8/5

=

1/7
_____
3/10

(two thirds over 8 fifths equals 1 seventh over 3 tenths).

How do I figure this out? (step by step explanation please).

I promise I will choose a best answer so you can get 10 points. :)

False
A proportion is a name we give to a statement that two ratios are equal
Seeing as these simplyfied are
14/21
--------- = .41666..
16/10
=
3/21
-------- = .476
3/10

Proportions must be equal

Need to simplify both before comparing:

(2 / 3) / (8 / 5)
(2 / 3) * (5 / 8)
10 / 24
5 / 12


(1 / 7) / (3 / 10)
(1 / 7) * (10 / 3)
10 / 21


No, these are not identical

(2/3) ÷ (8/5) is the same as (2/3) x (5/8) = 10/24
(1/7) ÷ (3/10) is the same as (1/7) x (10/3) = 10/21
false
