1day =13/4=3.25

12days=3.25×12=39

Answer 2

Given :

• Time of each class = 1 3/4 hours
• Discontinued her classes after = 12 days

To find :

• how many hours of classes did Nisha take

Steps :

• Here, we have to multiply the number of hours in each class by the number of days.

Solution :

⇒ Let's find the number of hours Nisha took.

Each class = 1 3/4

                  = 4 × 1 + 3/4

                  = 4 + 3/4

                  = 7/4

12 days = 12/1

             = 7/4 × 12/1

             = 7 × 21/4 × 1

             = 147/4

Therefore, Nisha attended 147/4 hours of Judo classes.
