Question

45:81 is equivalent to 85:_____​

Answer 1

Answer:

45:81 is equivalent to 85:153

Step-by-step explanation:

Given

44 : 81

Also it should be equivalent to 85 : x

where x is unknown

If two ratios a:b and c:d ratios are equivalent, then

a/b = c/d

That is,

45/81 = 85/x

$x =\frac{85*81}{45}$

=6885/45

= 153

So

44:81 = 85:153
