Answer 1

Answer:

• (a) Required Ratio is 1:3
• (b) Required Ratio is 4:15

Step-by-step explanation:

According to the Question

we have to calculate the Ratio

It is given that

(a). 30 min to 1.5 hours

Firstly we change the unit here

1.5 hours into min

→ 1.5 × 60 = 90 min

Now, calculating the ratio

→ Ratio = 30/90

→ Ratio = 1/3

→ Ratio = 1:3

• Hence, the required ratio is 1:3

b. 40 cm to 1.5 m

Conversion of Unit

1.5 m into cm

→ 1.5 × 100 = 150 cm

Now, calculating the ratio

→ Ratio = 40/150

→ Ratio = 4/15

→ Ratio = 4:15

• Hence, the required ratio is 4:15

Answer 2

Answer:

To find :-

• The ratio of 30 min to 1.5 hours.
• The ratio of 40 cm to 1.5 m.

Solution:-

1) »» 30 mins to 1.5 hours.

• »» 1.5 = 1.5 × 60 = 90 mins

Ratio is 30:90

»» 3/9

»» 3:9

Therefore, the required ratio is 3:9

2) »» 40 cm to 1.5 m.

• »» 1m = 100cm
• »» 1.5m = 1.5 × 100 = 150cm

Ratio is 40:150

»» 4/15

»» 4:15

Therefore, the required ratio is 4:15

Hope it helps you.
