Question

Are 12/102 and 18/153 equivalent ratios?

Answer 1

there are 2 ways:

`(12)/(102)` ?=
`(18)/(153)`

1) try to simplify

`(12)/(102)` (divide the numerator and denominator by 6) ?=
`(18)/(153)` (divide the numerator and denominator by 9)

2/17 = 2/17 so yes they are equivalent

2) use cross products

102x18 ?= 12x153

1836 = 1836 so yes they are equivalent
