Joji works 4 1 2 hours each day. How many hours does he work in 6 days ?

Given that, Joji works each day = 4 1 2 h o u r s = 4 × 2 + 1 2 h o u r s = 9 2 h o u r s Finding the Total Hours: To find the total hours, we need to multiply the number of hours worked per day by the number of days So, The Total hours will be taken by Joji = 9 2 × 6 h o u r s = 54 2 h o u r s = 27 h o u r s Hence, Joji works 27 h o u r s in 6 d a y s .

Calculate the following: 4 times 5 1 3

We need to find 4 times 5 1 3 . Thus, 4 × 5 1 3 Express the mixed fraction to improper fraction. ⇒ 4 × 16 3 ⇒ 4 × 16 3 ⇒ 64 3 Hence, the required answer is 64 3 .

Calculate the following: 4 1 3 times 5

We need to find 4 1 3 times 5 . Thus, 4 1 3 × 5 Express the mixed fraction to improper fraction. ⇒ 13 3 × 5 ⇒ 13 × 5 3 ⇒ 65 3 Hence, the required answer is 65 3 .

⇒ 1 1 2 t i m e s 2 3 = 2 × 1 + 1 2 t i m e s 2 3 = 3 2 t i m e s 2 3 = 3 2 × 2 3 = 3 × 2 2 × 3 = 6 6 = 1

Calculate the following : 2 5 t i m e s 2 1 2

⇒ 2 5 t i m e s 2 1 2 = 2 5 t i m e s 2 × 2 + 1 2 = 2 5 t i m e s 5 2 = 2 5 × 5 2 = 2 × 5 5 × 2 = 10 10 = 1

Calculate the following: 2 1 2 times 5 1 2

We know that, 2 1 2 times 5 1 2 means 2 1 2 × 5 1 2 . Express the mixed fraction to improper fraction: ⇒ 2 1 2 = 2 × 2 + 1 2 = 4 + 1 2 = 5 2 ⇒ 5 1 2 = 5 × 2 + 1 2 = 10 + 1 2 = 11 2 Thus, ⇒ 2 1 2 × 5 1 2 ⇒ 5 2 × 11 2 ⇒ 5 × 11 2 × 2 ⇒ 55 4 Writing the above fraction as mixed fraction ∴ 13 3 4 Hence, 2 1 2 times 5 1 2 is 13 3 4 .
