- John has an income of $30000 and he pays $6000 as income tax. Find the ratio of:

[A] His income tax to income

[B] Income to income tax

[A] Ratio of income tax to income = 6000:30000 = 6000/30000 = 1/5 = 1:5.

[B] Ratio of income to income tax = 30000:6000 = 30000:6000 = 5/1 = 5:1 - If Adam ran 2 km on Monday and ran just 500 m on Tuesday, then what is the ratio of distance run by Adam on Tuesday to Monday?
Therefore, ratio of distance run by Adam on Tuesday to Monday

= 500:2000

= 500/2000

= 1/4

= 1:4 - Jake works in a software company and earns $1000 per month. From that, he saves $200 per month. What is the ratio of Jake’s savings to income?
- The first and the fourth terms of a proportion are 9 and the second term is 27. Find out the third term?
Let the third term be ‘m’.

Therefore,

27 x m = 9 x 9 ( by cross product multiplication)

27m = 9 x 9

27m = 81

m = 81/27

m = 3Therefore, the 3rd term is 3

- Is the statement true?
