How do you simplify 14/24
Bond [772]

Answer:

7/12

Step-by-step explanation:

Simplification is something we can do if both the numerator and denominator are divisible by the same number.

In 14/24, both numbers are divisible by 2.

So, we divide both the numerator and denominator by 2. We get 7/12.

Therefore 14/24 = 7/12.

Are these numbers rational or irrational? √10 (square root of 10) √16 (square root of 16) 52% 1.235 1. Rational 2. Irrational pl
77julia77 [94]

Step-by-step explanation:

any rational number can be expressed as a/b, with a and b being integer numbers, and b different to 0.

-7 = -7/1 rational

sqrt(10) irrational (because there is no rational number multiplied by itself that results in 10)

sqrt(16) = sqrt(4×4) = 4 = 4/1 rational

52% = 52/100 rational

1.235 = 1235/1000 rational
