Question

Write each of the following ratios in the simplest form
(1) * 6.30: 16.80 (11) 3 weeks: 30 days
(iv) 48 min: 2 hours 40 min (v) 1 L 35 ml:270 ml
(ul) 3 m 5 cm: 35 cm
(vi) 4 kg: 2 kg 500 g​

Answer 1

Answer:

1.

$\frac{6.30}{16.80} = \frac{63}{168} = \frac{3}{8}$

6.30: 16.80=3:8

2.

3 weeks =21 days

$\frac{3 \: weeks}{30 \: days} = \frac{21 \: days}{30 \: days} = \frac{7 \: days}{10 \: days}$

3 weeks: 30 days=7 days:10 days

4.

2 hours 40 min =160 min

$\frac{48 \: min}{2 \: hours \: 40 \: min} = \frac{48 \: min}{160 \: min} = \frac{3 \: days}{10 \: days}$

48 min: 2 hours 40 min = 3 days : 10 days

5.

1 L 35 ml = 1035 ml

$\frac{1 \: l \: 35 \: ml}{270 \: ml} = \frac{1035 \: ml}{270 \: ml} = \frac{23 \: ml}{6 \: ml}$

1 L 35 ml:270 ml=23 ml : 6 ml

6.

3 m 5 cm = 35 cm

$\frac{3 \: m \: 5 \: cm}{35 \: cm} = \frac{35 \: cm}{35 \: cm} = \frac{1}{1}$

3 m 5 cm: 35 cm=1 cm: 1 cm

7.

4 kg = 4000 gm

2 kg 500 gm = 2500 gm

$\frac{4 \: k g}{2 \: kg \: 500g} = \frac{4000gm}{2500gm} = \frac{8gm}{5gm}$

4 kg: 2 kg 500 g= 8 gm : 5 gm
