Question

Divide


a) 20 hours 42 minutes by 9
b) 25 weeks 6 days 6 hours by 6​

Answer 1

Answer:

A) 138

B) 43464

Step-by-step explanation:

A)

20 * 60 = 1200

1200 + 42 = 1242

1242/9 = 138

B)

24 * 60 = 1440

1440 * 7 = 10080

10080 * 25 = 25200

24 * 60 = 1440

1440 * 6 = 8640

24 * 6 = 144

252000 + 8640 + 144 = 260784

260784/6 = 43464

Answer 2

Answer:

a) 2 hours, 18 minutes

b) 4 weeks, 2 days, 5 hours

Step-by-step explanation:

a) Step 1 - Divide 20 h by 9

Quotient = 2 hours, Remainder = 2 hours

Change 2 hours ( remainder ) to minutes;

2 × 60 = 120 min

Add 120 min and 42 min = 162 min

Step 2 - Divide 162 min by 9

Quotient = 18 min, Remainder = 0

Therefore, Answer = 2 hours, 18 minutes ( Quotients )

b) Step 1 - Divide 25 by 6

Quotient = 4 weeks, Remainder = 1 week

Change 1 week ( remainder ) to days;

1 × 7 = 7 days

Add 7 days and 6 days = 13 days

Step 2 - Divide 13 days by 6

Quotient = 2 days, Remainder = 1 day

Change 1 day ( remainder ) to hours;

1 × 24 = 24 hours

Add 24 hours and 6 hours = 30 hours

Step 3 - Divide 30 hours by 6

Quotient = 5 hours, Remainder = 0

Therefore, Answer = 4 weeks, 2 days, 5 hours ( Quotients )
