Answer:
a = 5/4
Step-by-step explanation:
To make the second number in this ratio be 1, you need to multiply the whole ratio by 7/4:
(7/4)(5/7) : (7/4)(4/7) = 5/4 : 1 = a : 1
a = 5/4
11/15 + 7 ⇒ rational ⇒ the sum of two rationals is always rational
√14+13 ⇒ irrational ⇒ the sum of a rational and an irrational is always irrational
30×√6 ⇒ irrational ⇒ the product of a nonzero rational and an irrational is always irrational
11/12 × 7/15 ⇒ rational ⇒ the product of two rationals is always rational
