Answer 1

Which ratio is less than 7/15?     ​

Repeating the successful method,

Let's make then all the same "size"

We have 7/15 = 21/45

and

A. 9/15 = 27/45

B. 2/5 = 18/45

C. 3/5 = 27/45

D. 24/45 = 25/45

By inspection, B = 18/45 is less than 7/15 = 21/45

Answer: B = 2/5

Answer 2

Here's the trick. All the given answers have denominators that divide into 45, so multiply each by 45, remembering that the denominator will divide into 45. Whatever the result of this division you multiply by the numerator. Write that down against each option: A 27; B 18; C 27; D 24. Now do the same for 7/15: 21. All you have to do now is look for numbers less than 21. B is the only one. By the way, note that A and C are the same!
