# Worksheet on Ratio in Lowest Term

Practice the questions given in the worksheet on ratio in lowest term. We know two or more quantities compared in a ratio must have the same units of measurement. So, the ratios have no unit. Then a ratio is expressed in its lowest term.

1. Find the ratio of the following in the simplest form:

(i) 2 dozens to 3 scores

(ii) 1 kg 200g and 1 kg 800g

(iii) 864 and 60

(iv) 1 .5 kg yo 15 g

(v) x$$^{2}$$ + 2x + 1 and x$$^{2}$$ - x -2

2. Find the ratio of the following in the simplest form:

(i) 40 ml to 2.4 l

(ii) 2$$\frac{1}{2}$$ hours to 50 minutes

(iii) \$ 1.40 and 67 cents

(iv) a$$^{3}$$ + b$$^{3}$$ and a$$^{2}$$ - b$$^{2}$$

3. Simplify the following ratios:

(i) 3$$\frac{1}{3}$$ : 2$$\frac{1}{2}$$

(ii) 2.5 : 6.5

(iii) 2$$\frac{1}{5}$$ : 1$$\frac{2}{15}$$ : $$\frac{3}{10}$$

Answers for the worksheet on ratio in lowest term are given below.

1. (i) 2 : 5

(ii) 2 : 3

(iii) 72 : 5

(iv) 100 : 1

(v) (x + 1) : (x - 2)

2. (i) 1 : 60

(ii) 3 : 1

(iii) 7 : 3

(iv) (a$$^{2}$$ - ab + b$$^{2}$$) : (a - b)

3. (i) 4 : 3

(ii) 5 : 13

(iii) 66 : 34 : 9
