5/6:7/10 what is simplest form of

Answer 1

You should have a list of properties and operations you can do with ratios

(5/6) : (7/10)
= (5/6)(30) : (7/10)(30) <---- I multiplied each term of my ratio by 30, which is the LCD of 6 and 10
= 25 : 21 <--- they have no common multiplier so that's it

or
ratios are simply fractions
so (5/6) : (7/10)
= (5/6) / (7/10)
recall how we divide fractions ....
= (5/6)(10/7)
= 50/42
= 25/21 or 25 : 21
