Question

Find the ratio of:

A) 4 weeks : 49 days

B) 3.75 kg : 750 g

C) 6m : 90cm

Answer 1

Given :

There are some numbers to find the ratio.

Solution :

A) 4 weeks : 49 days

Convert 4 weeks to days :

1 week = 7 days

4 weeks = 7 × 4 = 28 days

28 days : 49 days = $\frac{28}{49}$

Reduce it to the lowest = $\frac{4}{7}$

= 4 days : 7 days

B) 3.75 kg : 750 g

Convert 3.75 kg to gram

1 kg = 1000 grams

3.75 kg = 3.75 × 1000 = 3750 grams

3750 g : 750 g = $\frac{3750}{750}$

Reduce it to the lowest = $\frac{5}{1}$

= 5 g : 1 g

C) 6 meter : 90 cm

Convert 6 meter to centimeter.

1 meter = 100 cm

6 meter = 100 × 6 = 600 cm

600 cm : 90 cm = $\frac{600}{90}$

Reduce it to the lowest = $\frac{20}{3}$

= 20 cm : 3 cm

A) 4 : 7 (days)

B) 5 : 1 (grams)

C) 20 : 3 (cm)
