Question

find the ratio of a) 24 to 16 with full step pls and next question
b) 14 to 21 c) 90cm to 1.5 ​

Answer 1

Answer:

1 . 24/16 = 12/8 = 6/4 = 3/2

Ratio = 3:2

2. 14/21 = 2/3

Ratio = 2:3

3. 90/1.5 = 18/0.3 = 6/0.1

Ratio = 6:0.1 / 60:1

Answer 2

Answer:-

1. First find HCF of the two nos. (Highest common factor).

thus, HCF (24,16):

(HCF by listing method):-

24=1,24,2,12,3,8,4,6

16=1,16,2,8,4

hcf= 8

2. Now, divide the numerator and denominator by the HCF.

thus, 24/8= 3 and 16/8=2

3. Finally ratio = 3:2 (3 is to 2)

Similarly you can use these steps to find ratio of 14 to 21 and 90 cm to 1.5

b) 14 to 21:

hcf of 14 and 21 = 7

& 14/7 =2, 21/7=3.

so ratio = 2:3

c) (note that you haven't written the unit for 1.5, so I am considering metre as the unit.)

90 cm to 1.5 m

since 1.5 m = 1.5*100 = 150 cm

HCF of 90 and 150 =30

& 90/30 = 3, 150/30=5

so ratio = 3:5

(if considered cm as the unit of 1.5, then, ratio = 60:1)
