Step-by-step explanation:

TO FIND

The ratio of:

1. 30 days and 210 hours
2. 7 years and 18 months

Solving Q1:

Converting 30 days into hour:

We know,

• 1 day = 24 hours
• 30 days = (30 × 24) hours
• 30 days = 720 hours

Finding the ratio of 30 Days and 210 hours:

• 30 days : 210 hours
• 720 hours : 210 hours

Hours cancelled.

• 720 : 210
• (24 × 30) : (7 × 30)

30 cancelled.

• 24 : 7

Solving Q2:

Converting 7 years into months:

We know,

• 1 year = 12 months
• 7 years = (7 × 12) months
• 7 years = 84 months

Finding the ratio of 7 years and 18 Months:

• 7 years : 18 months
• 84 months : 18 months

Months cancelled.

• (14 × 6) : (3 × 6)

6 cancelled.

• 14 : 3

Answer 2

Answer:

1 day = 24 hours

30 days = (30 x 24) hours

30 days = 720 hours

So,

30 days : 210 hours • 720 hours : 210 hours

720: 210 • (24 x 30): (7 × 30)

• 24:7
