Question

express the following rational number simplest form @ -25/30 b)150/400 c)-8/120 d)22/144​

Answer 1

Answer:

a) -5/6

b) 3/8

c)-1/15

d)11/72

Step-by-step explanation:

to write the rational number in simplest form divide the the numerator and denominator by the highest common factor of them.

a) -25/30

HCF of 25 and 30 is 5 , then divide both the numbers by 5

so, -25/30 = -5/6

b) 150/400

HCF of 150 and 400 is 50, then divide both the numbers by 50

so , 150/400 = 3/8

c)-8/12

HCF OF 8 AND 12 is 8, then divide both the numbers by 8

so, -8/120= -1/15

d)22/144

HCF of 22 and 144 is 2, then divide both the numbers by 2

so, 22/144= 11/72
